1 00:08:10,800 --> 00:08:13,880 We don't know about the absolute dating in this site. 2 00:08:13,960 --> 00:08:18,600 This site was abandoned for so long and perhaps forgotten. 3 00:08:33,480 --> 00:08:37,960 The columnar joint is imported from another region, 4 00:08:38,039 --> 00:08:39,360 from another location. 5 00:09:05,200 --> 00:09:09,680 We are very surprised that this site consists of two cultural layers. 6 00:09:11,480 --> 00:09:15,600 The first layer on the surface, it's from 500 BC. 7 00:09:17,400 --> 00:09:19,080 But at four meters depth, 8 00:09:19,160 --> 00:09:21,480 we found another cultural layer. 9 00:09:22,320 --> 00:09:25,360 It is from 5,200 BC. 10 00:09:29,280 --> 00:09:31,800 It is very surprising. We are very shocked. 11 00:09:32,920 --> 00:09:34,000 It is very old. 12 00:10:00,680 --> 00:10:03,800 I'm not really sure about the function of this site. 13 00:10:03,880 --> 00:10:09,640 However, we've still not found a skeleton or human bone, 14 00:10:09,720 --> 00:10:11,760 so this is not a burial site. 15 00:10:12,680 --> 00:10:15,840 Perhaps it is for ceremonies or rituals. 16 00:11:38,880 --> 00:11:42,880 They are natural, but the position now is not in the natural position. 17 00:11:43,360 --> 00:11:45,640 -And normally vertical. -Vertical, yes. 18 00:11:45,720 --> 00:11:47,520 -That's right. -And here it's laid on its side. 19 00:11:47,600 --> 00:11:49,720 -Also, it's not cut like this. -Yeah. 20 00:11:49,800 --> 00:11:52,840 Here, all is cut into one or one-and-a-half meters. 21 00:12:01,280 --> 00:12:04,720 The natural position, there is no ground mass in between. 22 00:12:05,280 --> 00:12:06,680 It will be very tight together. 23 00:12:08,640 --> 00:12:12,160 But here, in between these columnar rocks, there is a mortar 24 00:12:12,240 --> 00:12:15,960 -that holds them together, like cement. -Yeah. 25 00:12:16,040 --> 00:12:19,240 The thickness is, like, five centimeters, and it's very consistent. 26 00:12:26,200 --> 00:12:28,120 Yes. Yeah. 27 00:13:36,640 --> 00:13:37,480 Yeah. 28 00:13:38,000 --> 00:13:40,920 It's not the same shape of pyramids 29 00:13:41,000 --> 00:13:43,760 like Mayan or Giza pyramids. 30 00:13:48,640 --> 00:13:50,680 Yeah. But it has circular features. 31 00:14:53,960 --> 00:14:56,400 So, we have three methods here. 32 00:14:56,480 --> 00:14:59,800 -The GPR. -Yeah, that's ground-penetrating radar. 33 00:14:59,880 --> 00:15:02,160 -Ground-penetrating radar, yes. -Yeah. 34 00:15:02,240 --> 00:15:05,000 -And resistivity tomography. -Yeah. 35 00:15:05,080 --> 00:15:07,160 And also the seismic tomography. 36 00:15:25,640 --> 00:15:29,000 We're going to do the ground-penetration radar, 37 00:15:29,080 --> 00:15:30,400 the GPR surveys. 38 00:15:43,440 --> 00:15:49,160 We chose the frequency of 40 megahertz to penetrate down to 30 meters. 39 00:16:30,840 --> 00:16:34,640 It has a seismic velocity of about 200 meters per second. 40 00:16:38,680 --> 00:16:39,720 That's a void. 41 00:16:41,480 --> 00:16:43,720 -A void. An empty space. -Empty. 42 00:16:46,280 --> 00:16:48,440 Yes, as you see here, it's rectangular. 43 00:16:50,080 --> 00:16:51,920 -And the spot is just right… -Yeah. 44 00:16:52,000 --> 00:16:54,160 -…because in the center of this site… -Right. 45 00:16:55,320 --> 00:16:57,960 …beneath the Terrace One, there is also a chamber… 46 00:17:00,200 --> 00:17:02,280 …connecting to this chamber 47 00:17:02,360 --> 00:17:04,160 beneath the second terrace. 48 00:17:44,920 --> 00:17:47,640 When we see these chambers… 49 00:17:47,720 --> 00:17:48,880 -Yeah. -…three chambers, 50 00:17:49,600 --> 00:17:51,600 it's just like, we were amazed. 51 00:19:44,080 --> 00:19:47,040 Okay. Layer four could be before 20,000. 52 00:19:47,120 --> 00:19:49,120 -Could be before 20,000. -Very old. 53 00:20:51,560 --> 00:20:55,440 -I think we know little about our history. -Right. 54 00:20:55,520 --> 00:20:57,720 I think we miss a big thing here. 55 00:29:38,800 --> 00:29:41,440 -They are still not accepting it. -Right. 56 00:29:41,520 --> 00:29:43,760 I regret because archaeologists, 57 00:29:43,840 --> 00:29:47,040 or any other researchers, just stop researching. 58 00:29:53,680 --> 00:29:56,800 If we could prove clearly, 59 00:29:56,880 --> 00:30:01,880 and accept there is advanced human cultures before 11,000 BC, 60 00:30:01,960 --> 00:30:03,200 that will be a big step.
