So what is it? 55 00:04:17,963 --> 00:04:21,163 Even from above, it's hard to get the full picture. 56 00:04:22,923 --> 00:04:26,483 But we have a good idea of the original layout of the site. 57 00:04:27,683 --> 00:04:30,523 And it's like nothing else from the ancient world. 58 00:04:34,723 --> 00:04:38,243 Mound A likely originally stood as high as 100 feet, 59 00:04:39,563 --> 00:04:41,843 anchoring a 43-acre plaza. 60 00:04:43,003 --> 00:04:45,243 With six concentric ridges, 61 00:04:45,323 --> 00:04:49,523 each perhaps as tall as six feet and leveled off at the top 62 00:04:49,603 --> 00:04:53,803 creating a half circle with a diameter of three quarters of a mile, 63 00:04:55,123 --> 00:04:57,283 broken up by a series of aisles, 64 00:04:57,363 --> 00:04:59,323 like some kind of amphitheater. 65 00:05:00,883 --> 00:05:05,483 And scattered nearby are no less than six massive man-made mounds 66 00:05:05,563 --> 00:05:09,123 labeled by archaeologists, simply "A" through "F". 67 00:05:14,803 --> 00:05:16,683 Poverty Point is one of the largest 68 00:05:16,763 --> 00:05:19,203 and most complex ancient sites in North America. 69 00:05:21,123 --> 00:05:25,363 Its oldest sections date back to 3,700 years ago… 70 00:05:26,843 --> 00:05:30,163 long before its builders farmed the land or kept livestock. 71 00:05:32,883 --> 00:05:35,283 And the ancient Americans of Poverty Point 72 00:05:35,363 --> 00:05:37,883 then spent the next 600 years 73 00:05:37,963 --> 00:05:41,123 continuously developing and improving the site. 74 00:05:43,883 --> 00:05:44,883 Why? 75 00:05:48,403 --> 00:05:50,403 No documents or traditions have survived 76 00:05:50,483 --> 00:05:53,283 to tell us what Poverty Point's purpose was. 77 00:05:53,363 --> 00:05:55,443 So archaeologists are left guessing. 78 00:05:57,523 --> 00:06:00,283 Site manager and historian, Mark Brink Jr., 79 00:06:00,363 --> 00:06:03,323 is the first to admit that mainstream archaeology 80 00:06:03,403 --> 00:06:06,963 hasn't been able to confirm much about this mysterious site. 81 00:06:08,163 --> 00:06:10,443 Tell me everything you know about this site. 82 00:06:10,523 --> 00:06:12,763 So Mound A is massive, 83 00:06:12,843 --> 00:06:17,483 the largest mound constructed in the Western Hemisphere at the time, 84 00:06:17,563 --> 00:06:20,963 which shows you that Poverty Point was the center of something truly big. 85 00:06:21,043 --> 00:06:24,043 It suggests, then, a strong motive behind it. 86 00:06:24,123 --> 00:06:26,963 Do you have any thoughts on what that motive could be? 87 00:06:27,043 --> 00:06:28,203 We really don't know. 88 00:06:28,283 --> 00:06:32,163 It was a ceremonial center for some reason, but we don't know yet. 89 00:06:32,243 --> 00:06:34,723 -Can we add the "yet"? -Yeah. 90 00:06:35,323 --> 00:06:36,603 We do have an idea 91 00:06:36,683 --> 00:06:40,123 as to why it was built here and not someplace else, 92 00:06:41,123 --> 00:06:45,963 and it has to do with an even more ancient site about two miles to the south. 93 00:06:46,043 --> 00:06:48,483 As we go south from Poverty Point 94 00:06:48,563 --> 00:06:50,563 we come to a place called Lower Jackson Mound. 95 00:06:50,643 --> 00:06:53,443 And the three principal mounds of Poverty Point 96 00:06:53,523 --> 00:06:57,843 are lined up precisely north-south with Lower Jackson Mound. 97 00:06:58,643 --> 00:07:01,443 And Lower Jackson Mound is much older than Poverty Point. 98 00:07:01,523 --> 00:07:06,683 It dates to 3500 BC, 5,500 years old. 99 00:07:06,763 --> 00:07:11,043 And yet, the makers of Poverty Point were not only aware of it, 100 00:07:11,123 --> 00:07:14,043 but they used it as the anchor of their whole site. 101 00:07:17,363 --> 00:07:19,883 Clearly the ancient builders understood geography 102 00:07:19,963 --> 00:07:22,323 and how to orient structures to true north. 103 00:07:23,563 --> 00:07:26,083 But there's something else going on here at Poverty Point 104 00:07:26,163 --> 00:07:28,883 that archaeologists don't like to acknowledge 105 00:07:29,603 --> 00:07:32,083 encoded in its unique geometry. 106 00:07:33,163 --> 00:07:37,523 You see, the flat horizon all around allows you to observe 107 00:07:37,603 --> 00:07:41,643 the rising and the setting of the Sun and the Moon and the stars. 108 00:07:44,283 --> 00:07:46,723 This is a place for astronomers. 109 00:07:52,003 --> 00:07:54,243 Most of us are not aware of this today. Why should we be? 110 00:07:54,323 --> 00:07:55,683 We live in light-polluted cities. 111 00:07:57,123 --> 00:07:59,043 We can hardly see the skies at all, 112 00:07:59,803 --> 00:08:02,643 but if you were the ancients and you studied the skies, 113 00:08:03,963 --> 00:08:06,043 you would notice this phenomenon. 114 00:08:07,523 --> 00:08:10,043 The Sun has its stopping points on the horizon. 115 00:08:10,123 --> 00:08:11,683 We call them the solstices. 116 00:08:11,763 --> 00:08:13,923 The Sun stops still on the summer solstice, 117 00:08:14,003 --> 00:08:16,243 stays roughly in the same place for two or three days, 118 00:08:16,323 --> 00:08:20,443 and then starts to move back like a pendulum swing along the horizon. 119 00:08:20,523 --> 00:08:22,043 Same on the winter solstice. 120 00:08:25,603 --> 00:08:30,043 Archaeoastronomer William Romain discovered that these important dates, 121 00:08:30,123 --> 00:08:34,843 the solstices, respectively the longest and shortest days of the year, 122 00:08:34,923 --> 00:08:36,923 were actually marked at Poverty Point 123 00:08:37,003 --> 00:08:39,763 by a skillfully designed system of alignments. 124 00:08:43,763 --> 00:08:46,683 If you stand at the eastern edge of the oval space 125 00:08:46,763 --> 00:08:48,483 at the heart of the plaza, 126 00:08:48,563 --> 00:08:52,843 the summer solstice sunset falls directly in line with Mound B, 127 00:08:52,923 --> 00:08:54,123 the oldest mound. 128 00:08:55,483 --> 00:08:57,203 And from the same vantage point, 129 00:08:57,283 --> 00:09:01,523 the winter solstice sunset falls directly behind Mound E. 130 00:09:02,803 --> 00:09:05,683 Move over to the western edge of that same inner oval, 131 00:09:05,763 --> 00:09:10,523 and you'll find that the summer solstice Sun rises directly over Mound C, 132 00:09:11,523 --> 00:09:15,443 while the winter solstice Sun rises directly over Mound D. 133 00:09:17,603 --> 00:09:21,443 And if you gaze directly west through the center of the plaza 134 00:09:21,523 --> 00:09:23,643 on either the spring or fall equinox, 135 00:09:24,803 --> 00:09:28,043 the Sun appears to roll down the northern edge of Mound A 136 00:09:28,123 --> 00:09:30,203 before sinking below the horizon. 137 00:09:36,603 --> 00:09:39,003 Poverty Point may have more intriguing structures 138 00:09:39,083 --> 00:09:41,443 designed to track changes in the sky. 139 00:09:42,683 --> 00:09:44,003 In one corner of the site, 140 00:09:44,083 --> 00:09:47,243 archaeologists found a large circle of holes 141 00:09:49,363 --> 00:09:51,803 marked today by restored white posts. 142 00:09:53,163 --> 00:09:57,003 We don't know how tall the original posts in those holes would have been, 143 00:09:57,843 --> 00:10:00,363 but in its overall conception and design, 144 00:10:00,443 --> 00:10:05,763 it reminds me of the prehistoric Woodhenge excavated near Stonehenge in England. 145 00:10:07,243 --> 00:10:12,443 What's unique about Poverty Point is how many woodhenges it boasts. 146 00:10:13,883 --> 00:10:16,203 These circles, how many of them are there here? 147 00:10:16,803 --> 00:10:19,643 Well, there's probably at least 40 of them. 148 00:10:20,603 --> 00:10:22,203 Scale? Across-- 149 00:10:22,283 --> 00:10:25,603 So, some of them are pretty small, maybe 60 feet in diameter, 150 00:10:25,683 --> 00:10:28,683 some are larger, 200 or more feet in diameter, 151 00:10:29,323 --> 00:10:32,043 but the dates on these vary wildly. 152 00:10:33,923 --> 00:10:36,603 [Graham] They were created over the course of hundreds of years, 153 00:10:37,283 --> 00:10:40,123 spanning generations of ancient Americans, 154 00:10:40,203 --> 00:10:43,283 who kept tweaking their position and size over time. 155 00:10:44,963 --> 00:10:47,563 I'm reminded of Malta where the megalith builders 156 00:10:47,643 --> 00:10:49,883 kept changing the orientation of their temples 157 00:10:49,963 --> 00:10:54,443 to face the star Sirius, culminating with Ġgantija. 158 00:10:55,603 --> 00:10:57,803 And of Göbekli Tepe in Turkey 159 00:10:57,883 --> 00:10:59,923 where the ancients built a series of temples 160 00:11:00,003 --> 00:11:02,603 over a period of about a thousand years, 161 00:11:02,683 --> 00:11:06,123 also, I believe, to track the movement of the stars. 162 00:11:07,763 --> 00:11:10,243 These are all massive projects, 163 00:11:10,323 --> 00:11:12,803 featuring structures repeatedly rebuilt 164 00:11:12,883 --> 00:11:16,483 and shifted in their orientation over generations. 165 00:11:17,603 --> 00:11:20,643 Could the multiple post circles of Poverty Point 166 00:11:20,723 --> 00:11:23,683 also have been designed to track something in the heavens? 167 00:11:25,963 --> 00:11:28,923 Sophisticated knowledge, true science 168 00:11:29,003 --> 00:11:32,083 is evidenced by the geometry and the astronomy of the site. 169 00:11:33,723 --> 00:11:36,403 Yet mainstream archaeologists are reluctant 170 00:11:36,483 --> 00:11:40,163 to recognize astronomy of any kind in Poverty Point's wood circles. 171 00:11:42,643 --> 00:11:45,043 -Here, I don't think they make sense. -Mmm-hmm. 172 00:11:45,123 --> 00:11:47,963 Why should the people who lived here and created this place, 173 00:11:48,043 --> 00:11:50,243 why should they not have been interested in the sky? 174 00:11:50,323 --> 00:11:51,843 -I'm not saying they weren't. -No. 175 00:11:51,923 --> 00:11:53,163 I bet they were. 176 00:11:53,243 --> 00:11:55,403 Okay. So what do you think the circles were used for? 177 00:11:56,243 --> 00:11:57,883 We don't know. We don't know yet 178 00:11:57,963 --> 00:11:59,963 if they were used for astronomy purposes or not. 179 00:12:00,043 --> 00:12:01,043 [Graham] Yeah. 180 00:12:02,683 --> 00:12:05,683 Ancient cultures were very fixated upon the sky. 181 00:12:07,083 --> 00:12:09,443 That notion isn't in itself disputed, 182 00:12:09,523 --> 00:12:11,683 but archaeology tends to regard it as irrelevant. 183 00:12:12,643 --> 00:12:14,603 I think that the reason is, in part, 184 00:12:14,683 --> 00:12:18,203 because most archaeologists just don't understand astronomy at all. 185 00:12:18,283 --> 00:12:20,083 It's not what they've been taught to do, 186 00:12:20,163 --> 00:12:22,603 and secondly, they regard it as an intrusion 187 00:12:22,683 --> 00:12:26,043 into their domain by outsiders. 188 00:12:30,123 --> 00:12:33,243 I'm not claiming that Poverty Point was created 189 00:12:33,323 --> 00:12:36,203 by the lost advanced civilization I'm looking for. 190 00:12:38,123 --> 00:12:40,323 But I'm interested in the origins 191 00:12:40,403 --> 00:12:42,843 of the sophisticated astronomy and geometry 192 00:12:42,923 --> 00:12:44,243 that were deployed here. 193 00:12:45,843 --> 00:12:48,523 There's evidence that advanced architectural, 194 00:12:48,603 --> 00:12:53,683 Earth-measuring and astronomical knowledge was inherited from earlier times, 195 00:12:53,763 --> 00:12:57,323 but inherited from whom and how much earlier? 196 00:12:59,923 --> 00:13:02,203 I'm not saying the ancient Americans living here 197 00:13:02,283 --> 00:13:04,963 weren't capable of discovering and incorporating 198 00:13:05,043 --> 00:13:09,003 these astronomical observations into their sites by themselves. 199 00:13:09,403 --> 00:13:10,563 On the contrary. 200 00:13:11,203 --> 00:13:12,483 I think we've passed the point 201 00:13:12,563 --> 00:13:15,443 where we should regard the Native American cultures 202 00:13:15,523 --> 00:13:17,203 as simply hunter-gatherers. 203 00:13:17,283 --> 00:13:21,043 They were much more complicated than that and much more sophisticated. 204 00:13:23,243 --> 00:13:26,203 And their vision of Earth's place in the cosmos 205 00:13:26,283 --> 00:13:28,643 expressed by the alignments at Poverty Point 206 00:13:28,723 --> 00:13:30,963 is essentially the same vision 207 00:13:31,043 --> 00:13:34,483 that we've seen in other ancient sites around the world, 208 00:13:34,563 --> 00:13:36,483 sharing the same focus 209 00:13:36,563 --> 00:13:39,043 on the sacred connection between Earth and sky. 210 00:13:45,803 --> 00:13:49,163 Poverty Point is just one of 800 Mound Builder sites 211 00:13:49,843 --> 00:13:52,323 surviving across the state of Louisiana. 212 00:13:53,323 --> 00:13:55,323 While in North America as a whole, 213 00:13:55,403 --> 00:13:59,363 out of an original estimated total of one million mounds, 214 00:13:59,443 --> 00:14:02,003 around 100,000 still remain. 215 00:14:04,163 --> 00:14:08,643 Amongst these, the most spectacular example of a mound 216 00:14:08,723 --> 00:14:11,443 expressing the sacred connection between Earth and sky, 217 00:14:12,363 --> 00:14:17,963 lies about 600 miles to the northeast of Poverty Point in Ohio, 218 00:14:19,003 --> 00:14:22,563 a site that may just hold the key to understanding what happened 219 00:14:22,643 --> 00:14:25,283 to the lost civilization I've been searching for. 220 00:14:28,323 --> 00:14:30,603 Perched atop a densely forested ridge 221 00:14:31,683 --> 00:14:34,563 lies a stunning example of an effigy mound. 222 00:14:36,843 --> 00:14:40,563 A gigantic earthwork shaped into the form of a living creature. 223 00:14:42,443 --> 00:14:45,603 In this case, a 400-meter-long snake. 224 00:14:48,123 --> 00:14:50,243 It's called Serpent Mound. 225 00:14:52,483 --> 00:14:54,443 Starting from its coiled tail, 226 00:14:54,523 --> 00:14:57,363 seven bends in its body wind their way to the head, 227 00:14:58,643 --> 00:15:03,363 where gaping jaws appear about to engulf a separate oval earthwork. 228 00:15:06,083 --> 00:15:09,643 Even from the air, it's hard to make out all the detail. 229 00:15:10,523 --> 00:15:14,963 But by taking into account new discoveries about its original construction 230 00:15:15,043 --> 00:15:16,523 and stripping away the trees, 231 00:15:17,163 --> 00:15:20,523 we can reveal what the effigy would have looked like in its prime. 232 00:15:25,483 --> 00:15:28,403 Serpent Mound extends more than quarter of a mile 233 00:15:28,483 --> 00:15:30,243 from its jaws in the northwest 234 00:15:30,323 --> 00:15:33,323 to its tail on the southwestern corner of the hilltop. 235 00:15:36,523 --> 00:15:40,243 Originally, there was a circle of standing stones by the head, 236 00:15:40,323 --> 00:15:41,643 function unknown. 237 00:15:43,123 --> 00:15:46,923 And just behind the head, two decorative extensions, 238 00:15:47,003 --> 00:15:48,883 function, likewise, unknown. 239 00:15:55,923 --> 00:15:59,363 Serpent Mound is a remarkable, graceful structure, 240 00:15:59,443 --> 00:16:02,483 one that instills wonder in those who visit. 241 00:16:03,843 --> 00:16:06,763 It's clearly an ancient and mysterious place. 242 00:16:06,843 --> 00:16:09,363 But who built the huge effigy, and why? 243 00:16:12,403 --> 00:16:17,283 The sign of the site will tell you it was built around 1000 AD 244 00:16:17,363 --> 00:16:21,163 by an indigenous people referred to as the Fort Ancient Culture. 245 00:16:22,723 --> 00:16:27,403 But the sign, like so many of these historical markers, is wrong. 246 00:16:28,923 --> 00:16:33,123 Truth is that nobody really knows how old Serpent Mound is. 247 00:16:35,243 --> 00:16:37,243 That date of 1000 AD 248 00:16:37,323 --> 00:16:40,283 was based on just two of the organic samples 249 00:16:40,363 --> 00:16:43,803 taken from parts of the mound that may have been later reconstructed, 250 00:16:45,323 --> 00:16:49,323 because another archaeological survey found samples from the serpent's base 251 00:16:49,403 --> 00:16:52,883 dating back to 321 BC. 252 00:16:54,523 --> 00:16:56,723 The evidence that Serpent Mound was 253 00:16:56,803 --> 00:16:59,683 the subject of a restoration is very clear. 254 00:16:59,763 --> 00:17:03,323 I suggest that these restorations go back deep into the past. 255 00:17:05,083 --> 00:17:08,243 There's just one problem with investigating my theory. 256 00:17:09,122 --> 00:17:13,362 The administrators of Serpent Mound have decided to ban me. 257 00:17:15,843 --> 00:17:20,043 We've made repeated efforts to get permission to film here, 258 00:17:20,122 --> 00:17:22,122 but they denied us that permission. 259 00:17:24,243 --> 00:17:29,243 On what I regard as ideological and indeed rather personal grounds, 260 00:17:29,323 --> 00:17:31,203 let me read from their email. 261 00:17:33,122 --> 00:17:34,643 "Our role is to ensure that 262 00:17:34,723 --> 00:17:37,283 Serpent Mound's integrity and preservation, 263 00:17:37,363 --> 00:17:38,403 both physically 264 00:17:38,483 --> 00:17:41,563 and in its historical interpretation, are maintained." 265 00:17:42,523 --> 00:17:47,243 "Because the presenter of this series, Graham Hancock, 266 00:17:47,323 --> 00:17:51,083 proposes a theory and story that do not align 267 00:17:51,163 --> 00:17:54,923 with what we know to be true about Serpent Mound, 268 00:17:55,003 --> 00:17:57,523 your request is declined." 269 00:18:00,323 --> 00:18:05,483 A correct word for this so-called mission to protect the interpretation of the site 270 00:18:05,563 --> 00:18:07,963 is, of course, censorship. 271 00:18:08,043 --> 00:18:10,483 And what more effective way 272 00:18:10,563 --> 00:18:16,403 for archaeologists to censor and restrain and crush opposing views 273 00:18:16,483 --> 00:18:20,123 than to deny access to archaeological sites? 274 00:18:21,883 --> 00:18:24,563 It's by no means the first time this has happened. 275 00:18:24,643 --> 00:18:29,083 This unfortunately is systematic and consistent behavior 276 00:18:29,163 --> 00:18:30,243 amongst archaeologists. 277 00:18:30,323 --> 00:18:32,163 They do practice censorship. 278 00:18:32,243 --> 00:18:37,603 They practice censorship by ridiculing and insulting alternative ideas. 279 00:18:39,803 --> 00:18:43,083 So what exactly is it in this theory of mine 280 00:18:43,163 --> 00:18:45,403 that's deemed so objectionable? 281 00:18:46,883 --> 00:18:49,843 Quite simply, it's because I dare to suggest 282 00:18:49,923 --> 00:18:53,283 that the idea behind the design of Serpent Mound 283 00:18:53,363 --> 00:18:57,523 goes back to a time much earlier than 300 BC, 284 00:18:58,683 --> 00:19:03,243 more than 10,000 years earlier to the end of the last Ice Age. 285 00:19:05,243 --> 00:19:11,003 And for me, the proof of this lies in one of its most stunning attributes, 286 00:19:11,083 --> 00:19:14,403 one that mainstream archaeologists don't like to acknowledge. 287 00:19:15,043 --> 00:19:17,923 Because again, it involves the sky. 288 00:19:20,003 --> 00:19:25,003 If you overfly Serpent Mound on the summer solstice around June 21st, 289 00:19:25,083 --> 00:19:27,843 you'll immediately notice that the jaws of the serpent 290 00:19:27,923 --> 00:19:32,163 are aligned almost directly to the point where the Sun sets. 291 00:19:34,923 --> 00:19:38,923 So this is what happens at sunset on the summer solstice. 292 00:19:39,003 --> 00:19:42,723 You see the head of the serpent, it seems to be seeking out the Sun, 293 00:19:42,803 --> 00:19:45,803 and then as the Sun begins to go down, you get it more clearly, 294 00:19:45,883 --> 00:19:49,563 this beautiful alignment between Earth and sky, 295 00:19:49,643 --> 00:19:52,403 then the majesty of the site just overwhelms you. 296 00:19:54,363 --> 00:19:57,483 It's obvious to anybody today 297 00:19:57,563 --> 00:20:01,043 that that is what the head of the great serpent is pointing at. 298 00:20:01,643 --> 00:20:06,443 But that idea was ignored and rejected by archaeology for a very long time. 299 00:20:07,323 --> 00:20:10,003 The organization, which runs the site, 300 00:20:10,083 --> 00:20:13,843 has allowed an enormous number of trees to grow up around the head of the serpent. 301 00:20:13,923 --> 00:20:17,043 I think they believe it provides shade to tourists. 302 00:20:17,123 --> 00:20:20,483 But what it does is it limits that massive impact 303 00:20:20,563 --> 00:20:23,843 of seeing the head of the serpent pointing directly at the setting Sun. 304 00:20:28,123 --> 00:20:32,083 Jeff Wilson, who owns much of the property next to the ancient effigy, 305 00:20:32,163 --> 00:20:36,123 is the president of an independent group called The Friends of Serpent Mound, 306 00:20:37,203 --> 00:20:41,843 dedicated to preserving and promoting this and other Native American sites. 307 00:20:43,043 --> 00:20:46,203 Clearly Serpent Mound is very important to you. 308 00:20:46,283 --> 00:20:48,483 Yes, it's very personal to me. 309 00:20:48,563 --> 00:20:52,443 It's one of the most spiritual places I've ever visited. 310 00:20:52,523 --> 00:20:53,843 It's a sacred place. 311 00:20:53,923 --> 00:20:55,243 When you encounter it, 312 00:20:55,323 --> 00:20:59,483 you walk away feeling changed by the experience when you come here. 313 00:21:03,003 --> 00:21:06,203 It's the most amazing archaeoastronomy site in North America, 314 00:21:06,283 --> 00:21:07,123 -bar none. -Yes. 315 00:21:09,203 --> 00:21:13,003 What makes it so is the recent confirmation that the Mound Builders 316 00:21:13,083 --> 00:21:16,963 cleverly incorporated a whole series of sky ground alignments 317 00:21:17,043 --> 00:21:18,683 into Serpent Mound's design. 318 00:21:22,643 --> 00:21:25,083 The center of the second bend behind the head 319 00:21:25,163 --> 00:21:28,923 points eastward to where the Sun rises on the summer solstice, 320 00:21:31,043 --> 00:21:33,003 and the center of the following bend 321 00:21:33,083 --> 00:21:36,483 targets the sunrise on the spring and fall equinoxes 322 00:21:36,563 --> 00:21:39,123 when night and day are of equal length. 323 00:21:41,483 --> 00:21:43,523 While the center of the final bend 324 00:21:43,603 --> 00:21:46,843 is aimed where the Sun rises on the winter solstice, 325 00:21:46,923 --> 00:21:48,803 the shortest day of the year. 326 00:21:50,363 --> 00:21:52,923 As for that intricately coiled tail, 327 00:21:53,643 --> 00:21:56,883 if you draw a straight line from its exact center 328 00:21:56,963 --> 00:21:59,083 through the hinge of the serpent's jaws, 329 00:21:59,163 --> 00:22:03,443 you'll find it's precisely oriented to true astronomical north. 330 00:22:07,323 --> 00:22:10,283 To construct it and to figure out 331 00:22:10,363 --> 00:22:14,323 where all these astronomical alignments that are incorporated into its design 332 00:22:14,403 --> 00:22:16,523 is just an amazing sheer work of genius… 333 00:22:16,603 --> 00:22:17,883 It's a work of genius, yeah. 334 00:22:17,963 --> 00:22:19,563 …from the prehistoric Native Americans. 335 00:22:19,643 --> 00:22:23,203 Yeah. And that genius is easily overlooked, actually. 336 00:22:23,283 --> 00:22:26,603 Is archaeology taking the astronomy of this site seriously? 337 00:22:26,683 --> 00:22:29,043 Are enough archaeologists taking it seriously? 338 00:22:29,123 --> 00:22:31,123 I don't think so, no. 339 00:22:31,203 --> 00:22:32,403 Um… 340 00:22:32,483 --> 00:22:37,323 There's very few people that even pay attention to it or consider it. 341 00:22:41,843 --> 00:22:45,043 It's as though mainstream archaeologists want us to believe 342 00:22:45,123 --> 00:22:48,803 that all these astronomical alignments happen by accident. 343 00:22:50,243 --> 00:22:55,243 I think it's fair to say that there were people in ancient Native America 344 00:22:55,323 --> 00:22:59,803 with advanced surveying, geometrical and astronomical skills, 345 00:22:59,883 --> 00:23:03,243 and they put those skills to work in the creation of enormous monuments, 346 00:23:03,323 --> 00:23:06,683 most of which have tragically been swept away. 347 00:23:08,603 --> 00:23:13,803 These precise solar alignments manifested on such a gigantic scale 348 00:23:13,883 --> 00:23:16,803 represent an extraordinary achievement for hunter-gatherers 349 00:23:16,883 --> 00:23:18,923 living in the 3rd century BC. 350 00:23:20,483 --> 00:23:24,123 But there's evidence suggesting that the ridge where Serpent Mound sits 351 00:23:24,203 --> 00:23:27,963 was considered sacred for thousands of years before that. 352 00:23:29,643 --> 00:23:33,403 Every single culture that ever existed here, 353 00:23:33,483 --> 00:23:37,923 dating back to the last Ice Age, left cultural remains at Serpent Mound. 354 00:23:38,003 --> 00:23:41,123 What it says to me, this continuous human presence here, 355 00:23:41,803 --> 00:23:45,643 it kind of suggests to me that the site's been sacred for a very long time. 356 00:23:45,723 --> 00:23:46,563 Right. 357 00:23:46,643 --> 00:23:48,803 It seems to me that should be taken into account 358 00:23:48,883 --> 00:23:50,563 in the archaeological narrative. 359 00:23:50,643 --> 00:23:52,683 It should be part of the story of Serpent Mound. 360 00:23:52,763 --> 00:23:53,603 Yes. 361 00:23:56,563 --> 00:24:00,403 Archaeologists have been wrong before and they could be wrong again. 362 00:24:01,003 --> 00:24:05,763 All in all, it's obvious that the origins of Serpent Mound are complicated. 363 00:24:07,123 --> 00:24:12,123 What if 321 BC doesn't mark the year of Serpent Mound's construction, 364 00:24:12,803 --> 00:24:15,363 but one of its many reconstructions? 365 00:24:17,643 --> 00:24:20,603 Let's not forget we're dealing with a serpent here, 366 00:24:20,683 --> 00:24:24,923 and that serpents are creatures renowned for their ability to change their skin. 367 00:24:26,843 --> 00:24:31,243 It's a possibility actually suggested by Serpent Mound's unique alignment. 368 00:24:32,123 --> 00:24:34,843 You see, it isn't quite perfect. 369 00:24:36,963 --> 00:24:40,523 Today the summer solstice Sun, as viewed from Serpent Mound, 370 00:24:40,603 --> 00:24:44,723 actually sets about two degrees off the exact center of the jaws. 371 00:24:45,883 --> 00:24:47,923 Seems close enough to the naked eye. 372 00:24:49,883 --> 00:24:54,123 But it's hard to believe that the people who conceived of and created 373 00:24:54,203 --> 00:24:58,283 this sophisticated effigy mound, tracking all those calendar moments, 374 00:24:58,923 --> 00:25:02,883 would go to all this trouble and not get it exactly right. 375 00:25:04,603 --> 00:25:06,483 I think they did get it right. 376 00:25:08,323 --> 00:25:12,283 It all has to do with the way the Earth shifts on its axis over the millennia. 377 00:25:13,843 --> 00:25:16,283 In a phenomenon long known to astronomers 378 00:25:16,883 --> 00:25:20,163 who refer to it as the obliquity of the ecliptic. 379 00:25:21,123 --> 00:25:22,483 To put it in simple terms, 380 00:25:22,563 --> 00:25:24,763 the Earth, as we know, is tilted on its axis, 381 00:25:24,843 --> 00:25:27,163 but that tilt is not fixed and constant. 382 00:25:27,243 --> 00:25:30,723 It changes over a 41,000-year cycle. 383 00:25:30,803 --> 00:25:33,563 It changes roughly two-and-a-half degrees over that cycle. 384 00:25:33,643 --> 00:25:35,163 It nods back and forward, 385 00:25:35,843 --> 00:25:40,083 and that affects the rising position of the Sun on the summer solstice. 386 00:25:42,683 --> 00:25:44,763 Instead of asking why the serpent's jaws 387 00:25:44,843 --> 00:25:48,123 aren't perfectly aligned to the summer solstice sunset, 388 00:25:49,843 --> 00:25:52,123 what if we asked a different question? 389 00:25:53,403 --> 00:25:57,763 When, if one takes into account this obliquity of the ecliptic, 390 00:25:57,843 --> 00:26:01,723 did the gaping jaws and the setting Sun line up perfectly? 391 00:26:05,843 --> 00:26:08,243 Turns out it wasn't a thousand years ago, 392 00:26:08,323 --> 00:26:10,723 or even 2,300 years ago, 393 00:26:10,803 --> 00:26:14,283 when archaeologists insist Serpent Mound was first constructed. 394 00:26:15,243 --> 00:26:18,843 The serpent's mouth was exactly centered on the Sun 395 00:26:18,923 --> 00:26:21,963 around 12,800 years ago 396 00:26:23,083 --> 00:26:24,843 at the end of the last Ice Age, 397 00:26:27,323 --> 00:26:29,123 when the ridge on which the serpent was built 398 00:26:29,203 --> 00:26:33,483 itself occupied an extraordinarily significant spot. 399 00:26:37,883 --> 00:26:42,763 At the very peak of the Ice Age, around 20,000 years ago, 400 00:26:42,843 --> 00:26:48,043 much of North America was covered by an immense ice cap over a mile deep. 401 00:26:51,083 --> 00:26:55,643 Today, Ohio's Serpent Mound Valley is a forest-covered wilderness, 402 00:26:56,243 --> 00:26:58,363 but let's not look at it as it is now. 403 00:26:59,243 --> 00:27:02,763 Let's look at it as it was during the last Ice Age. 404 00:27:04,163 --> 00:27:08,123 This very valley, where the great serpent was constructed, 405 00:27:08,203 --> 00:27:12,603 actually marks the furthest south that the North American ice sheet reached. 406 00:27:13,803 --> 00:27:17,283 The giant ice cliffs rising just by this ridge 407 00:27:17,363 --> 00:27:20,283 would have looked like something out of a fantasy novel. 408 00:27:21,443 --> 00:27:23,763 To the people who lived through this period, 409 00:27:23,843 --> 00:27:27,403 it must have seemed that some benign magical power was at work. 410 00:27:29,283 --> 00:27:32,843 But any celebration of the halt of the ice would have been short-lived, 411 00:27:34,203 --> 00:27:37,323 because sometime around 12,800 years ago, 412 00:27:38,003 --> 00:27:41,763 when the serpent was perfectly aligned with the summer solstice, 413 00:27:41,843 --> 00:27:45,123 something huge was happening all over the planet. 414 00:27:45,683 --> 00:27:46,523 [thunderclap] 415 00:27:46,603 --> 00:27:48,803 Something apocalyptic 416 00:27:50,603 --> 00:27:52,283 called the Younger Dryas. 417 00:27:53,643 --> 00:27:57,723 It was a period of radical climate change and rising sea levels. 418 00:27:59,843 --> 00:28:02,523 Humanity survived, but barely. 419 00:28:09,443 --> 00:28:14,363 I find it intriguing, by means of its alignment to the summer solstice sunset, 420 00:28:15,123 --> 00:28:19,843 that Serpent Mound serves as a signpost, a date stamp, 421 00:28:19,923 --> 00:28:24,483 drawing our attention to the skies of 12,800 years ago, 422 00:28:24,563 --> 00:28:28,003 a time when we know there was a global cataclysm 423 00:28:28,083 --> 00:28:31,043 big enough to have destroyed an advanced civilization. 424 00:28:34,643 --> 00:28:37,043 Again, I'm reminded of Göbekli Tepe, 425 00:28:37,123 --> 00:28:40,803 where figures of creatures carved into one of the most spectacular pillars 426 00:28:41,443 --> 00:28:45,203 seem to depict the position of the stars at the summer solstice 427 00:28:45,283 --> 00:28:47,283 during the time of the Younger Dryas. 428 00:28:48,963 --> 00:28:53,243 It's no accident in my view that the serpent's solstitial alignment 429 00:28:53,323 --> 00:28:56,443 also speaks to that same cataclysmic epoch. 430 00:28:57,883 --> 00:28:59,363 But why a serpent? 431 00:29:04,403 --> 00:29:06,163 Of the greatest relevance, I think, 432 00:29:06,243 --> 00:29:08,763 are numerous Native American myths and traditions 433 00:29:08,843 --> 00:29:14,003 in which giant serpents are directly associated with cataclysmic Earth changes. 434 00:29:16,803 --> 00:29:19,163 There's an ancient legend of the Iroquois 435 00:29:19,243 --> 00:29:23,563 whose domain at the height of their power extended deep into Ohio. 436 00:29:23,643 --> 00:29:27,483 The villain of the legend is a giant horned serpent. 437 00:29:30,923 --> 00:29:34,563 Long ago, a village was plagued by a great serpent 438 00:29:34,643 --> 00:29:36,283 who dwelt in a nearby lake. 439 00:29:37,123 --> 00:29:41,563 So the great spirit in the sky sent down a hero to defeat him. 440 00:29:43,283 --> 00:29:47,123 In a vicious battle, bolts of lightning struck the serpent, 441 00:29:48,483 --> 00:29:52,043 the sound shook the Earth, and the flashes were so bright 442 00:29:52,123 --> 00:29:56,803 that the people shielded their eyes, covered their ears, and hid in fear. 443 00:29:58,563 --> 00:30:02,363 The very constellations were dislodged from the night sky 444 00:30:02,443 --> 00:30:07,283 and came crashing to Earth with a ferocious blast and scorching heat. 445 00:30:07,363 --> 00:30:10,763 One star fell into the lake, wounding the horned serpent. 446 00:30:13,083 --> 00:30:15,963 As the great serpent thrashed its tail in pain, 447 00:30:16,043 --> 00:30:17,643 it sent 100-foot waves 448 00:30:17,723 --> 00:30:20,883 crashing through the valleys in a series of colossal floods. 449 00:30:22,643 --> 00:30:26,843 Most of the tribe didn't survive, but the serpent was driven away. 450 00:30:30,883 --> 00:30:35,643 We've already seen such serpent imagery in ancient monuments all over the world. 451 00:30:37,043 --> 00:30:38,323 On the temples in Mexico, 452 00:30:38,403 --> 00:30:41,803 dedicated to Quetzalcoatl, the feathered serpent, 453 00:30:42,403 --> 00:30:45,523 carved into the temple of Ġgantija on Malta, 454 00:30:46,243 --> 00:30:49,843 and raining down from the skies on the pillars of Göbekli Tepe. 455 00:30:51,203 --> 00:30:52,923 It's a powerful symbol 456 00:30:53,003 --> 00:30:56,283 found at sites that invite us to look to the heavens. 457 00:30:57,723 --> 00:30:58,803 Why? 458 00:31:00,803 --> 00:31:05,003 I think this Iroquois legend has more than a kernel of truth to it. 459 00:31:05,083 --> 00:31:06,483 Perhaps the stars, 460 00:31:06,563 --> 00:31:10,203 or something resembling stars, did fall to Earth. 461 00:31:10,283 --> 00:31:12,523 Perhaps there was great flooding afterwards, 462 00:31:12,603 --> 00:31:16,483 part of those earthshaking cataclysms of the Younger Dryas. 463 00:31:18,603 --> 00:31:20,683 If the original version of Serpent Mound 464 00:31:20,763 --> 00:31:25,283 was designed sometime around the end of the last Ice Age, as I believe, 465 00:31:25,363 --> 00:31:29,643 then perhaps it was intended to carry a message to the future, 466 00:31:29,723 --> 00:31:34,323 a warning even, as to what caused that apocalyptic series of events 467 00:31:34,403 --> 00:31:36,643 around 12,800 years ago, 468 00:31:37,283 --> 00:31:42,043 a warning to look to the heavens for stars falling from the sky. 469 00:31:46,123 --> 00:31:48,083 A quarter of the way around the Earth, 470 00:31:48,163 --> 00:31:51,683 there's evidence that other ancient peoples also lived in terror 471 00:31:51,763 --> 00:31:53,603 of just such a threat from above, 472 00:31:54,563 --> 00:31:56,763 and took steps to protect themselves 473 00:31:56,843 --> 00:32:00,403 deep in the heart of Cappadocia in modern-day Turkey, 474 00:32:01,163 --> 00:32:03,123 which is where I'm heading next.
