I don't mean that rhetorically, I certainly don't have any level of specialized knowledge in the area. Thus my curiosity.

I understand. There is a continuous life history in the fossil record for the last 600 million plus years. About 540 million years ago life exploded in diversity. In Canada and China there are very limited occurrences of fossils of Chordates and Vertebrates. Very rare. Those are our most distant ancestors. The large vertebrates in Cretaceous (145 to 66 million years ago)for instance are the dinosaurs. Then 66 or so million years ago they went mostly extinct and some evolved into birds. After that time there is the rise in the next class of vertebrates, mammals (we included). But our mammalian man like ancestors are fairly recent the last 10 million years and less. And man (Homo sapiens) is on the order of 600 to 700,000 years old. I'm probably off on some of the year numbers but am mostly correct. If there was an advanced civilization previously we would seen their fossils, buildings, parking lots and ships and plastic in the fossil record. We are the pinnacle and end product of it all right now. Bear with me man because geology can be tedious and boring. I hope this helps.
