See Graham Hancock’s “America Before”, or just follow the latest results of DNA and blood group tracings for ancient populations ... no aliens required, rather it is necessary to think in a different manner that we do today (logical as opposed to symbolic thinking) to even begin to understand anything the ancients achieved.

Also keep in mind that most of the very ancient world in now under many hundreds of feet of water, silt and mud.

I like Graham Hancock's work, for suggesting possibilities, not for his supposed proof. If Hancock is right, genetic analysis, undersea shipwrecks, advances in technology, and mainstream archeology should eventually provide it. Eventually.
