Ok so this is my first thread so go easy on me
)
This was sort of inspired by the ancient aliens thread.
Does anyone think it's possible that we (humans) are not the first intelligent life form that the earth has ever produced?
I got thinking about this after seeing a program a while ago called life after people. It was about how the world would look and what would happen if people suddenly disappeared and nature was left to take over again. What surprised me was how fast things would disappear. I think they said after about 1000 years then nearly everything we have built, all out cites and things will be almost all gone, and after one million years there would be nothing left to show we were ever here apart from a few odd strata in the rocks and the stuff we left on the moon. Now i know that if there was life as advanced as us then we would have probably found some sort of evidence by now but what if they weren't quite as advanced? Say they got up to about the mid Victorian level of tech or something.
