Mankind is about 140,000 years old, give or take. The oldest continuous culture is an aboriginal tribe at about 40,000 years. That leaves about 100,000 years unaccounted for. Oh yes, there were civilizations before the current one.

Ok, so why haven’t we found evidence for it?

They have found some interesting stuff really deep underground. But most of it is probably underwater now. The surface of the planet is constantly changing. And there is a vast area under the oceans that no one has ever explored. I think we just haven’t looked in the right places yet.

It’s hard to evaluate your claim when you don’t provide any specific information.

The surface of the planet hasn't changed that drastically in 140000 years. Sea levels varied, but the oceans and continents have been in almost exactly the same places.

There are no secret hidden cities at the bottom of the ocean that were above water 140000 years ago. Small settlements just offshore, yes. But in open ocean, no.

Over 80% of the ocean floor has never been explored by man.
