Note - Archeological Evidence Pointing More To Ice-Age Super-Civs

Sophisticated mega constructions ... oft all that survive
all those centuries ... keep getting re-dated earlier and
earlier. Some, Sardinia esp, look to date into the middle
of the ice age ... >12,000 years. Some pre-Incan structures
seem to fit the same bill.

Some TV idiots like to claim 'aliens' or 'god-like beings'
were responsible. Kinda doubt it. The old structures are
damned good, but not 'alien civ' sophisticated. Hey, humans
are CLEVER - don't necessarily NEED 'aliens'.

HOW some of these things were built, STILL a big mystery
however ... it'd be super-difficult even with modern
methods/machines.

Maybe the oldest thing anyone wants to ADMIT to are
the Gobekli Tepe 'temples' ... WAY better than
Stonehenge. 10-12000 years old. Was NOT so long ago
that humans were assumed to be near-animal idiots,
incapable of such engineering/cooperation that long
ago. For some reason we always want to de-rate The
Ancients ... likely so WE can feel all superior now.

Clearly some really funky stuff was happening during
the last ice age. Alas a lot of it was probably
coastal civs - now 300+ feet underwater. "High Tech"
civs ... um ... no, not likely. High-tech leaves
LOTS of signs, a huge garbage footprint, and so far
we haven't seen those.
