The USA southwest has high water signature.
Richard Dewhurst who is archived here in search
records giants living in organized community along an
ancient shoreline.....now 5000ft above sea level
They lived beside an ancient inland sea which is gone.
Several places USA southwest had high water for vast distances
How and why the waters went away is debate.
The ice sheets over north america broke several times to
cascade and auger out extant river outlets...such as the Columbia.
Many rivers were flowing incredible metric volume as the surges
lasted for days to weeks.
The terrain scars remain to this day...have books or video programs
showing the evidence/archeao and hypothetical track to surmise
the ice sheet break up.
The USA southwest has surging waters and standing waters.
This accounts for some**of the erosion left as evidence in the
sweeping vistas : )
South America/Puma Punku region has terrain upheavel evidence.
Posnansky discovered flood detritus layered upon ground which was
seared by some regional fire conflaguration.
In this detritus...he found skulls with the 3x elongation
This race perished in the chaos.
Andean region uplift is also debate.
Evidence of stranded ancient shoreline 5000ft above sea level exist
and were noted by Darwins son?...who surveyed the region (apology
if ref is incorrect for exact name as Im going from memory from decade +back in time)
The chaos which tumbled the Andes and Puma Punku indicates
races existed before and survived the cataclysm.
For me...it reasons that races were mobil upon earths ancient
That they were able to migrate to North and South America.
The Earth itself is question
Expanding Earth theory which has decade+ teacher links this website
comments that expansion events release voluminous waters under
pressure from earths crustal zones.
This release period would = rapid ice sheet building in colder climates
allong with torential rains in warmer.
World oceans would rise....waters would build to depths on land
until wall breach...where breach = terrain scarring.
Causality driver for the 10'000 bc window
numerous theories for causality.
Its possible that the Solar System experienced some dynamic
influence which caused Earth changes accross the board.
Velikovsky opined that the chaos was repeated intersects which
continued all the way into the Bronze age.
The terrain scars
The technology signature of races who are mobil and global
From WW2....technology went from biplane to pulse detonation
engines via German/Horten bros...flying wing.
Note....US use scramjet and pulse detonation aircraft which are
Alot can happen in 6 years.
Defining ancient technology is tricky.
Mythology and ruins indicate they could and did.
Apart from labels....some race is doing this...and crossing world seas : )
