1 00:00:03,500 --> 00:00:11,380 Did you know the first humans appeared on Earth over one million years ago? 2 00:00:12,380 --> 00:00:14,179 That's a really long time. 3 00:00:15,279 --> 00:00:18,559 And we call this period prehistory. 4 00:00:22,760 --> 00:00:24,859 The first humans were nomads. 5 00:00:25,500 --> 00:00:29,780 That means they moved from place to place on foot. 6 00:00:29,780 --> 00:00:36,780 They gathered wild plants, they caught fish, and they hunted animals. 7 00:00:36,780 --> 00:00:52,210 They lived together in huts or caves, in small family groups called tribes. 8 00:00:52,210 --> 00:01:02,549 During this time, they discovered how to make fire. 9 00:01:02,549 --> 00:01:10,549 They used it for cooking, heating, for light, and to scare away animals. 10 00:01:10,549 --> 00:01:23,319 This was a very important discovery. Gradually, humans started to learn more skills. 11 00:01:23,319 --> 00:01:32,319 And about 10,000 years ago, people learned to cultivate plants and take care of animals. 12 00:01:32,319 --> 00:01:46,379 This was the beginning of farming. They stopped moving from place to place and they became sedentary. 13 00:01:46,379 --> 00:01:55,280 They built houses, small huts, took care of their animals, and grew their crops. 14 00:02:00,640 --> 00:02:09,139 Then about 8,000 years ago, people started to work with metals to make tools and weapons. 15 00:02:11,770 --> 00:02:14,349 And then they invented the wheel. 16 00:02:15,090 --> 00:02:21,770 This was a very important invention, because it meant they could travel more easily. 17 00:02:21,770 --> 00:02:37,919 in simple cars. At the same time, they also discovered how to make sailing boats, so they 18 00:02:37,919 --> 00:02:48,569 could move on water as well. As it was easier for them to move from place to place, they 19 00:02:48,569 --> 00:02:56,259 began to train with other people. And this is the end of Prehistory.
