1 00:08:10,843 --> 00:08:13,923 We don't know about the absolute dating in this site. 2 00:08:14,003 --> 00:08:18,643 This site was abandoned for so long and perhaps forgotten. 3 00:08:33,523 --> 00:08:38,003 The columnar joint is imported from another region, 4 00:08:38,082 --> 00:08:39,403 from another location. 5 00:09:05,243 --> 00:09:09,723 We are very surprised that this site consists of two cultural layers. 6 00:09:11,523 --> 00:09:15,643 The first layer on the surface, it's from 500 BC. 7 00:09:17,443 --> 00:09:19,123 But at four meters depth, 8 00:09:19,203 --> 00:09:21,523 we found another cultural layer. 9 00:09:22,363 --> 00:09:25,403 It is from 5,200 BC. 10 00:09:29,323 --> 00:09:31,843 It is very surprising. We are very shocked. 11 00:09:32,963 --> 00:09:34,043 It is very old. 12 00:10:00,723 --> 00:10:03,843 I'm not really sure about the function of this site. 13 00:10:03,923 --> 00:10:09,683 However, we've still not found a skeleton or human bone, 14 00:10:09,763 --> 00:10:11,803 so this is not a burial site. 15 00:10:12,723 --> 00:10:15,883 Perhaps it is for ceremonies or rituals. 16 00:11:38,923 --> 00:11:42,923 They are natural, but the position now is not in the natural position. 17 00:11:43,403 --> 00:11:45,683 -And normally vertical. -Vertical, yes. 18 00:11:45,763 --> 00:11:47,563 -That's right. -And here it's laid on its side. 19 00:11:47,643 --> 00:11:49,763 -Also, it's not cut like this. -Yeah. 20 00:11:49,843 --> 00:11:52,883 Here, all is cut into one or one-and-a-half meters. 21 00:12:01,323 --> 00:12:04,763 The natural position, there is no ground mass in between. 22 00:12:05,323 --> 00:12:06,723 It will be very tight together. 23 00:12:08,683 --> 00:12:12,203 But here, in between these columnar rocks, there is a mortar 24 00:12:12,283 --> 00:12:16,003 -that holds them together, like cement. -Yeah. 25 00:12:16,083 --> 00:12:19,283 The thickness is, like, five centimeters, and it's very consistent. 26 00:12:26,243 --> 00:12:28,163 Yes. Yeah. 27 00:13:36,683 --> 00:13:37,523 Yeah. 28 00:13:38,043 --> 00:13:40,963 It's not the same shape of pyramids 29 00:13:41,043 --> 00:13:43,803 like Mayan or Giza pyramids. 30 00:13:48,683 --> 00:13:50,723 Yeah. But it has circular features. 31 00:14:54,003 --> 00:14:56,443 So, we have three methods here. 32 00:14:56,523 --> 00:14:59,843 -The GPR. -Yeah, that's ground-penetrating radar. 33 00:14:59,923 --> 00:15:02,203 -Ground-penetrating radar, yes. -Yeah. 34 00:15:02,283 --> 00:15:05,043 -And resistivity tomography. -Yeah. 35 00:15:05,123 --> 00:15:07,203 And also the seismic tomography. 36 00:15:25,683 --> 00:15:29,043 We're going to do the ground-penetration radar, 37 00:15:29,123 --> 00:15:30,443 the GPR surveys. 38 00:15:43,483 --> 00:15:49,203 We chose the frequency of 40 megahertz to penetrate down to 30 meters. 39 00:16:30,883 --> 00:16:34,683 It has a seismic velocity of about 200 meters per second. 40 00:16:38,723 --> 00:16:39,763 That's a void. 41 00:16:41,523 --> 00:16:43,763 -A void. An empty space. -Empty. 42 00:16:46,323 --> 00:16:48,483 Yes, as you see here, it's rectangular. 43 00:16:50,123 --> 00:16:51,963 -And the spot is just right… -Yeah. 44 00:16:52,043 --> 00:16:54,203 -…because in the center of this site… -Right. 45 00:16:55,363 --> 00:16:58,003 …beneath the Terrace One, there is also a chamber… 46 00:17:00,243 --> 00:17:02,323 …connecting to this chamber 47 00:17:02,403 --> 00:17:04,203 beneath the second terrace. 48 00:17:44,963 --> 00:17:47,683 When we see these chambers… 49 00:17:47,763 --> 00:17:48,923 -Yeah. -…three chambers, 50 00:17:49,643 --> 00:17:51,643 it's just like, we were amazed. 51 00:19:44,123 --> 00:19:47,083 Okay. Layer four could be before 20,000. 52 00:19:47,163 --> 00:19:49,163 -Could be before 20,000. -Very old. 53 00:20:51,603 --> 00:20:55,483 -I think we know little about our history. -Right. 54 00:20:55,563 --> 00:20:57,763 I think we miss a big thing here. 55 00:29:38,843 --> 00:29:41,483 -They are still not accepting it. -Right. 56 00:29:41,563 --> 00:29:43,803 I regret because archaeologists, 57 00:29:43,883 --> 00:29:47,083 or any other researchers, just stop researching. 58 00:29:53,723 --> 00:29:56,843 If we could prove clearly, 59 00:29:56,923 --> 00:30:01,923 and accept there is advanced human cultures before 11,000 BC, 60 00:30:02,003 --> 00:30:03,243 that will be a big step.
