Did you happen to read, “Fingerprints of the Gods” by Graham Hitchcock? The whole book is about the possibility of civilizations existing before what is commonly accepted. He went off the rails when he asserted that they had been concentrated on Antarctica, but he has since recanted, and said basically what you did.....which is we can’t see much of the evidence of earlier civilizations because they are all under water after the ice sheets melted. I find myself believing it.

I happen to agree with that assumption. Where what we call Antartica before the tectonic plate separations existed is in a temprate/ tropic hospitable area for habitation for eons than what it was today. Many of the finds that have been discovered in Africa are in a region which was connected to that land mass.
Where and when that possibility of a prior suggestion of a civilization can only be reinforced is when there are more finds on the periphery of land masses prior to that massive upheaval on previous pieces of that super continent. The point being we should keep an open mind on discovery
