I've copied this over from the old forum so it can be shot down in flames all over again
I was watching a programme a while ago, I think called "Life After People"
It's basic conclusion was that, if all humans suddenly vanished from the Earth, it would only take at most, 200,000 years before any alien civilisation visiting would not be able to find a single trace of our ever having existed in the first place.
Everything, even the hardest of our stone structures would have been reclaimed by the environment.
My question is therefore this.
After 65 to perhaps over 100 million years, had there been a dinosaur civilisation on a par with maybe the ancient Egyptians, what evidence would be left today and how easy would it be to find it and identify it correctly?
Is it simply human arrogance to assume that we are the first 'peoples' of the Earth?
