| Woolly mammoths roamed the Earth for at least half a million years, coexisting with humans for millennia before finally going extinct some 4,000 years ago. That's a long time, but it's not that long in the grand scheme of things. For perspective, consider the fact that woolly mammoths were still alive when the pyramids of Egypt were being built. That speaks to both how long one of history's most famous empires lasted — Egypt existed for more than 3,000 years, making it 15 times older than the United States — as well as how relatively recently the elephantlike creatures existed. |
