I think to believe we have any reliable understanding of ancient civilizations and the like is naive.
Follow me here...
There's sort of a desert belt around the earth - sw, c north america, north/most of africa, mid east, curving south to austrailia. Shouldnt these
areas be plush, green, and teeming with life according to their latitudinal positions?
Consider the possibility that someone had taken issue with the ancient peoples for one reason or another and decided they were unfit for existence and
adopted a "scorched earth policy". Perhaps some type of beam was fired from outside the atmosphere, descimatiing all it contacted. It may have
started in sw america and followed the easerly route alluded to above. Ending up in austrailia, leaving behind nothing but the huge hole in the ozone
which was left by the beam and a bunch of sandy earth (and some formidable stone structures).
