Because those that could survive 119 00:06:50,580 --> 00:06:53,420 both the nuclear winter and the alien virus 120 00:06:53,540 --> 00:06:58,050 emerged as a profoundly altered and improved species. 121 00:06:59,920 --> 00:07:02,340 It was immediately following this event 122 00:07:02,470 --> 00:07:04,930 that humans first began to leave evidence 123 00:07:05,050 --> 00:07:09,390 of symbolic thinking, art, music and advanced language. 124 00:07:09,510 --> 00:07:12,020 Somehow, human beings 125 00:07:12,140 --> 00:07:15,060 reached another stage of evolution. 126 00:07:15,190 --> 00:07:20,030 It was the transformation of the human brain. 127 00:07:20,150 --> 00:07:24,530 Could it be, and we believe it did happen, 128 00:07:24,660 --> 00:07:28,370 that alien viruses infected Planet Earth 129 00:07:28,490 --> 00:07:30,330 at this inflection point 130 00:07:30,450 --> 00:07:33,120 of the extinction of the human species. 131 00:07:33,250 --> 00:07:36,790 They implanted viruses in the human species 132 00:07:36,920 --> 00:07:39,340 that changed the brain. 133 00:07:39,460 --> 00:07:42,510 NARRATOR: But could viruses really survive 134 00:07:42,630 --> 00:07:45,470 in the frozen vacuum of space? 135 00:07:45,590 --> 00:07:48,180 And if so, could they have come here 136 00:07:48,300 --> 00:07:50,680 not by accident, but as some kind 137 00:07:50,810 --> 00:07:53,230 of extraterrestrial invasion? 138 00:07:55,060 --> 00:07:58,560 Ancient astronaut theorists say yes and suggest 139 00:07:58,690 --> 00:08:01,900 further clues might be found by examining a controversial 140 00:08:02,030 --> 00:08:05,530 theory that comets, far from being lifeless, 141 00:08:05,650 --> 00:08:09,160 are brimming with alien microbes 142 00:08:09,280 --> 00:08:12,040 and

00:08:38,900 they suffer from severe bleeding 149 00:08:39,020 --> 00:08:41,440 and they are foaming at the mouth. 150 00:08:41,570 --> 00:08:47,240 The next day, eight more arrive with the same symptoms. 151 00:08:47,360 --> 00:08:51,950 And, in just a few weeks, thousands die, 152 00:08:52,080 --> 00:08:55,950 as Boston falls into the grip of one of the deadliest 153 00:08:56,080 --> 00:09:00,540 viral outbreaks of all time, the Spanish flu. 154 00:09:00,670 --> 00:09:03,500 FISHER: The 1918 Spanish flu epidemic 155 00:09:03,630 --> 00:09:08,010 is probably the worst epidemic in recorded human history. 156 00:09:09,550 --> 00:09:10,840 Medical historians estimate 157 00:09:10,970 --> 00:09:12,300 that up to 20 million 158 00:09:12,430 --> 00:09:14,720 people, uh, died during that epidemic. 159 00:09:14,850 --> 00:09:16,980 BIRNES: It didn't just focus 160 00:09:17,100 --> 00:09:19,140 on one group of people. 161 00:09:19,270 --> 00:09:22,020 People from the very top echelon of society 162 00:09:22,150 --> 00:09:24,360 all the way to the working poor 163 00:09:24,480 --> 00:09:27,150 were struck down by the Spanish flu. 164 00:09:31,780 --> 00:09:33,870 NARRATOR: Half a world away, the same 165 00:09:33,990 --> 00:09:37,830 influenza epidemic ravages populations across India. 166 00:09:37,950 --> 00:09:42,210 Its starting point is traced back to the city of Bombay. 167 00:09:42,330 --> 00:09:46,590 And there's a strange connection between these two outbreaks: 168 00:09:46,710 --> 00:09:51,010 They began on the same day. 169 00:09:51,130 --> 00:09:53,760 One of the things that's not often discussed 170 00:09:53,890 --> 00:09:56,430 is that the great flu epidemic began 171 00:09:56,560 --> 00:09:59,600 on the same day in two different places: 172 00:09:59,730 --> 00:10:04,440 In Boston and on the other side of the world in Bombay. 173 00:10:04,560 --> 00:10:06,480 Now, those are two spots on the Earth 174 00:10:06,610 --> 00:10:08,530 that are virtually on opposite ends 175 00:10:08,650 --> 00:10:11,950 and you have to wonder how that is possible because 176 00:10:12,070 --> 00:10:17,700 you can't travel, within a day, by ship from Boston to India. 177 00:10:17,830 --> 00:10:20,830 And air travel, at the time, didn't exist. 178 00:10:20,960 --> 00:10:23,500 IMBROGNO: How does an outbreak occur 179 00:10:23,630 --> 00:10:26,340 of the same virus on places 180 00:10:26,460 --> 00:10:29,260 so spread apart 181 00:10:29,380 --> 00:10:33,340 in 1918 in less than 24 hours? 182 00:10:33,470 --> 00:10:39,390 The answer is that the virus probably fell from space. 183 00:10:39,520 --> 00:10:45,020 Perhaps the Earth was grazed by the tail of a comet... 184 00:10:47,190 --> 00:10:50,490 and so that's why we had the outbreak of the epidemic 185 00:10:50,610 --> 00:10:52,610 on two sides of the planet. 186 00:10:54,240 --> 00:10:56,160 NARRATOR: Until recently, 187 00:10:56,280 --> 00:11:00,000 it was believed that radiation, extreme temperatures 188 00:11:00,120 --> 00:11:02,080 and the vacuum of space... 189 00:11:02,210 --> 00:11:04,620 That is to say, the absence of any oxygen... 190 00:11:04,750 --> 00:11:08,040 Would kill any life-form. 191 00:11:08,170 --> 00:11:10,010 - ASTRONAUT: Pressurization, go Atlas. - ASTRONAUT 2: Go Centaur. 192 00:11:10,130 --> 00:11:13,010 NARRATOR: But ever since humans first ventured into space, 193 00:11:13,130 --> 00:11:17,760 scientists have been finding evidence to the contrary. 194 00:11:26,350 --> 00:11:28,320 NASA's unmanned Surveyor 3 lander 195 00:11:28,440 --> 00:11:31,400 touches down on the Moon 196 00:11:31,530 --> 00:11:33,780 and begins its mission collecting soil 197 00:11:33,900 --> 00:11:36,570 from the lunar surface. 198 00:11:36,700 --> 00:11:39,200 Two years later, 199 00:11:39,330 --> 00:11:41,700 astronauts on the Apollo 12 mission 200 00:11:41,830 --> 00:11:46,500 recover parts of Surveyor 3 and return them to Earth. 201 00:11:46,630 --> 00:11:50,250 To the astonishment of scientists, 202 00:11:50,380 --> 00:11:54,220 living strep bacteria is found on the probe. 203 00:11:54,340 --> 00:11:58,890 But this is only the first of many cases of microorganisms 204 00:11:59,010 --> 00:12:01,260 surviving space travel. 205 00:12:03,850 --> 00:12:05,140 HOOVER: There have been experiments 206 00:12:05,270 --> 00:12:08,100 in which microorganisms have been flown 207 00:12:08,230 --> 00:12:10,270 to the International Space Station 208 00:12:10,400 --> 00:12:13,940 and exposed to the hard vacuum and the radiation 209 00:12:14,070 --> 00:12:16,950 and the temperature changes of deep space. 210 00:12:17,070 --> 00:12:19,320 And many of those organisms survived. 211 00:12:20,870 --> 00:12:22,870 NARRATOR: Incredibly, 212 00:12:22,990 --> 00:12:26,120 several types of bacteria have thrived back on Earth 213 00:12:26,250 --> 00:12:28,290 after spending up to two years 214 00:12:28,420 --> 00:12:31,210 outside the International Space Station. 215 00:12:31,340 --> 00:12:35,470 But even more surprisingly, this durability isn't reserved 216 00:12:35,590 --> 00:12:38,340 for single-celled organisms alone. 217 00:12:38,470 --> 00:12:43,350 In September 2007, a Russian Soyuz rocket 218 00:12:43,470 --> 00:12:46,980 carried tiny animals called tardigrades into space 219 00:12:47,100 --> 00:12:48,650 to test their legendary ability 220 00:12:48,770 --> 00:12:52,730 to thrive in extreme environments. 221 00:12:52,860 --> 00:12:55,190 HOOVER: Tardigrades are called water bears. 222 00:12:55,320 --> 00:12:59,200 Uh, they're found in the polar regions on mosses and so forth, 223 00:12:59,320 --> 00:13:01,200 and they're beautiful little animals. 224 00:13:01,320 --> 00:13:04,740 They have a very unusual life history, 225 00:13:04,870 --> 00:13:07,830 and there were experiments in which tardigrades were carried 226 00:13:07,960 --> 00:13:09,870 to the International Space Station, 227 00:13:10,000 --> 00:13:12,630 and they were found to survive exposure 228 00:13:12,750 --> 00:13:15,050 to the deep space environment. 229 00:13:15,170 --> 00:13:17,220 And after they were brought back, 230 00:13:17,340 --> 00:13:18,930 there were several of the tardigrades 231 00:13:19,050 --> 00:13:21,930 that were still alive. 232 00:13:22,050 --> 00:13:26,930 Now, in the last 20 years, it was shown beyond any doubt 233 00:13:27,060 --> 00:13:30,600 that microbes are essentially born space travelers. 234 00:13:30,730 --> 00:13:34,980 They can survive almost any of the rigors that you can think of 235 00:13:35,110 --> 00:13:36,940 that would greet them in space. 236 00:13:37,070 --> 00:13:38,400 High temperatures, 237 00:13:38,530 --> 00:13:40,490 high radiation, 238 00:13:40,610 --> 00:13:41,990 intense cooling 239 00:13:42,120 --> 00:13:44,780 and even intense heating. 240 00:13:44,910 --> 00:13:48,750 It's also well established that microorganisms can 241 00:13:48,870 --> 00:13:52,630 very easily survive in bodies like comets 242 00:13:52,750 --> 00:13:57,420 and could well live in bodies like Europa and Enceladus 243 00:13:57,550 --> 00:14:02,010 because there is ice there, there is liquid water oceans 244 00:14:02,140 --> 00:14:05,350 underneath the icy crust. 245 00:14:05,470 --> 00:14:08,350 NARRATOR: In recent years, astronomers are identifying 246 00:14:08,480 --> 00:14:12,690 more and more planets that could potentially harbor life. 247 00:14:12,810 --> 00:14:15,820 Some believe that microbial life 248 00:14:15,940 --> 00:14:18,940 first evolved on one of these distant planets. 249 00:14:21,400 --> 00:14:25,870 Eons later, meteor impacts blasted some of them into space, 250 00:14:25,990 --> 00:14:29,000 where they took root in comets. 251 00:14:29,120 --> 00:14:30,750 But even if true, 252 00:14:30,870 --> 00:14:33,830 how could they descend to Earth and infect humans? 253 00:14:33,960 --> 00:14:37,670 HOOVER: We know for a fact that material from other bodies 254 00:14:37,800 --> 00:14:41,260 in our solar system is continually raining down 255 00:14:41,380 --> 00:14:43,340 on the surface of the planet Earth, 256 00:14:43,470 --> 00:14:46,550 and it could well be bringing with it dead 257 00:14:46,680 --> 00:14:49,810 and possibly even living microorganisms 258 00:14:49,930 --> 00:14:53,310 as it enters the Earth's atmosphere and then lands 259 00:14:53,440 --> 00:14:56,690 in oceans or lakes or streams of the planet. 260 00:14:56,820 --> 00:14:59,980 NARRATOR: Could this explain many of the plagues 261 00:15:00,110 --> 00:15:02,950 that sickened and killed millions throughout history? 262 00:15:03,070 --> 00:15:08,330 In 2007, an international team of researchers set up 263 00:15:08,450 --> 00:15:12,160 a research facility in the Sierra Nevada mountains of Spain 264 00:15:12,290 --> 00:15:15,960 to collect data on microbes falling to Earth from the sky. 265 00:15:16,080 --> 00:15:20,300 What they discovered remains controversial. 266 00:15:20,420 --> 00:15:23,260 The total amount of viruses 267 00:15:23,380 --> 00:15:26,470 that were falling down on the Earth 268 00:15:26,590 --> 00:15:31,720 was something like 800 million individual viruses 269 00:15:31,850 --> 00:15:35,190 per square meter of the Earth. 270 00:15:35,310 --> 00:15:37,150 The conclusion they came to, of course, was that 271 00:15:37,270 --> 00:15:40,280 this was essentially viruses that were lofted 272 00:15:40,400 --> 00:15:42,490 from the surface of the Earth, 273 00:15:42,610 --> 00:15:46,030 taken up to the clouds and brought back. 274 00:15:46,160 --> 00:15:50,370 Now, I think some would have been recirculated in this way, 275 00:15:50,490 --> 00:15:52,410 but not all, 276 00:15:52,540 --> 00:15:55,540 and I feel that this is 277 00:15:55,670 --> 00:16:00,710 one of the most striking examples of science 278 00:16:00,840 --> 00:16:05,680 being essentially dishonest in its conclusions. 279 00:16:05,800 --> 00:16:10,890 These 800 million viruses per square meter 280 00:16:11,010 --> 00:16:15,020 falling on the Earth must include viruses 281 00:16:15,140 --> 00:16:17,190 that are coming from outside. 282 00:16:19,770 --> 00:16:21,690 NARRATOR: Although some scientists believe 283 00:16:21,820 --> 00:16:24,110 that life on Earth actually originated 284 00:16:24,240 --> 00:16:28,110 with microbes that rained down from comets, 285 00:16:28,240 --> 00:16:31,080 a theory known as panspermia, 286 00:16:31,200 --> 00:16:33,370 an even more controversial theory 287 00:16:33,500 --> 00:16:35,830 called directed panspermia 288 00:16:35,960 --> 00:16:41,290 proposes that these comets were sent here not by accident, 289 00:16:41,420 --> 00:16:44,010 but deliberately. 290 00:16:45,260 --> 00:16:48,470 If I'm an alien species, 291 00:16:48,590 --> 00:16:52,640 and I want to start a colony on a different planet, 292 00:16:52,760 --> 00:16:54,600 think of what we're doing now. 293 00:16:54,720 --> 00:16:59,600 We want to send human beings back to the Moon. 294 00:16:59,730 --> 00:17:02,770 We want to send human beings to Mars. 295 00:17:02,900 --> 00:17:05,690 What if that's not what they did? 296 00:17:05,820 --> 00:17:11,660 What if the ancient aliens didn't send complete life-forms, 297 00:17:11,780 --> 00:17:17,290 but sent submicroscopic life-forms? 298 00:17:17,410 --> 00:17:20,670 NARRATOR: Mainstream scientists remain skeptical 299 00:17:20,790 --> 00:17:23,670 that microbes can survive for thousands of years 300 00:17:23,800 --> 00:17:28,880 inside icy comets, much less that they might be sent to Earth 301 00:17:29,010 --> 00:17:31,590 deliberately to alter human evolution. 302 00:17:33,350 --> 00:17:35,390 But others argue that the proof 303 00:17:35,520 --> 00:17:37,810 can be found right here on Earth, 304 00:17:37,930 --> 00:17:40,850 in the closest environment we have to comets: 305 00:17:40,980 --> 00:17:44,520 The icy depths of glaciers. 306 00:17:51,030 --> 00:17:55,120 TSOUKALOS: April 17, 2019.. 307 00:17:55,240 --> 00:17:59,040 Ancient astronaut theorist Giorgio Tsoukalos 308 00:17:59,160 --> 00:18:02,420 and retired NASA scientist Dr. Richard Hoover 309 00:18:02,540 --> 00:18:05,710 are about to board a helicopter bound for a massive ice cave 310 00:18:05,840 --> 00:18:07,300 in the Canadian wilderness. 311 00:18:07,420 --> 00:18:08,880 All right, you ready for this? 312 00:18:09,010 --> 00:18:11,180 - Yes, absolutely. - All right. 313 00:18:11,300 --> 00:18:14,970 NARRATOR: Dr. Hoover spent most of his career studying fossils 314 00:18:15,100 --> 00:18:18,350 for signs of extraterrestrial microscopic life, 315 00:18:18,470 --> 00:18:21,190 and is a leading proponent of panspermia, 316 00:18:21,310 --> 00:18:24,480 the idea that life on Earth originally rained down 317 00:18:24,610 --> 00:18:26,690 from comets in outer space. 318 00:18:30,110 --> 00:18:32,240 He has invited Giorgio to accompany him 319 00:18:32,360 --> 00:18:34,530 while he investigates the Whistler ice cave... 320 00:18:34,660 --> 00:18:36,330 I always love this. 321 00:18:36,450 --> 00:18:38,160 NARRATOR: Where he is confident they will find 322 00:18:38,290 --> 00:18:40,160 the glacial ice teeming with microbial 323 00:18:40,290 --> 00:18:44,670 and perhaps even more sophisticated life-forms. 324 00:18:44,790 --> 00:18:48,000 Life-forms that may be thousands of years old. 325 00:18:48,130 --> 00:18:50,010 HOOVER: Oh, this is just... 326 00:18:50,130 --> 00:18:53,180 - absolutely magnificent. - It really is. 327 00:18:53,300 --> 00:18:55,470 NARRATOR: If alien viruses are reaching Earth, 328 00:18:55,600 --> 00:18:58,970 Dr. Hoover suggests that those that don't find a host 329 00:18:59,100 --> 00:19:01,480 could survive within such an environment 330 00:19:01,600 --> 00:19:04,270 for long periods of time. 331 00:19:04,400 --> 00:19:05,980 Today, he'll examine the glacier 332 00:19:06,110 --> 00:19:09,900 for the perfect samples to analyze in his laboratory. 333 00:19:10,030 --> 00:19:12,320 So, Richard, how excited are you to be here 334 00:19:12,450 --> 00:19:14,410 to conduct this experiment? 335 00:19:14,530 --> 00:19:16,660 (chuckles): Well, I'm tremendously excited. 336 00:19:16,780 --> 00:19:20,160 - This-this is absolutely a-a marvelous opportunity... - Yeah. 337 00:19:20,290 --> 00:19:23,080 To do more studies of life in ice. 338 00:19:23,210 --> 00:19:26,960 NARRATOR: After a 20-minute helicopter ride, the team arrives 339 00:19:27,090 --> 00:19:30,130 at the Whistler ice cave in the Pemberton glacier. 340 00:19:31,760 --> 00:19:33,590 TSOUKALOS: Wow. 341 00:19:33,720 --> 00:19:37,390 - This is incredible. - HOOVER: Yeah, amazing. 342 00:19:38,600 --> 00:19:40,310 HOOVER: Look at that. 343 00:19:40,430 --> 00:19:43,770 There must be a thousand shades of blue in this ice cave. 344 00:19:43,890 --> 00:19:45,940 Just absolutely fantastic. 345 00:19:48,230 --> 00:19:51,690 And here we see all of these magnificent shades of blue, 346 00:19:51,820 --> 00:19:55,150 and up there you see big streaks of black. 347 00:19:55,280 --> 00:19:58,780 Glaciers like to eat rocks, and as they eat rocks, 348 00:19:58,910 --> 00:20:02,370 the rocks gather inside, and when the sun shines 349 00:20:02,500 --> 00:20:04,290 through the ice and hits the rocks, 350 00:20:04,410 --> 00:20:08,080 it can cause it to melt and form nice little pools of water, 351 00:20:08,210 --> 00:20:11,710 and then when bacteria and algae grow in there 352 00:20:11,840 --> 00:20:15,590 and respire and produce their... their photosynthetic products, 353 00:20:15,720 --> 00:20:17,010 they make their own atmosphere. 354 00:20:17,140 --> 00:20:18,590 So, around every tiny rock 355 00:20:18,720 --> 00:20:21,930 in this glacier, there is a tiny planetary system 356 00:20:22,060 --> 00:20:25,060 with its own biology, its own atmosphere, 357 00:20:25,180 --> 00:20:29,150 its own soil, in effect. And its own oceans. 358 00:20:29,270 --> 00:20:32,190 NARRATOR: The ice here is tens of thousands of years old. 359 00:20:32,320 --> 00:20:35,820 But Dr. Hoover believes it is teeming with life. 360 00:20:35,950 --> 00:20:37,700 Wow.
