I've always been confused by the idea that we know all civilisation that has happened on earth, human or otherwise. Written record doesn't go back very far at all, and even archeological evidence is lacking.
Its believed that homo sapiens have been around for at least 300,000 years and yet we think almost all of that was entirely without civilization.
We find fossil records of dinosaurs but we have little to no evidence of what would have been before them, presumably there was an extinction event prior to them as well.
It seems foolish to think we are the latest incarnation of the only chain of civilization that had ever happened on Earth.
