While we’re trying to discover life beyond the Earth, there’s another curiosity about the Earth. Do you think there civilization on the Earth before human life began? Because the Earth is millions of years old, it’s possible that we had at least another species or two that were just as civilized and technologically advanced as humans. In fact, the last mass civilization like we have today could’ve been wiped out by that asteroid from 65 million years ago.
Part of the reason why it’s possible that civilized life existed before humanity is because any geological evidence of that could be obliterated by natural changes. Structures may last hundreds of years, if not, thousands of years, but geological processes can wipe all that out after it’s been a million years. So while we don’t have evidence that a past civilization from that far may have existed, such evidence can’t last for over a million years. Even today’s buildings, life, and products could disappear after another million years. But since we weren’t there, we wouldn’t know if something like that existed.
