The pre-Columbian “civilizations” give, I believe, a window into the character of the civilizations of the antediluvian world. Cultures long lost to time, lost to memory, and sunken in the rising seas at the end of the last ice age.

Lots of weirdness, coupled with some remarkable accomplishments.

Interesting concept, and not all that far fetched. God did rearrange the land masses at theme of the flood. After all the one one continent of the pre flood world was populated by probably over 8 to 10 billion people. After God created the continents the evidence of antediluvian would be on every known modern continent and island along with the evidence we see around the world under the oceans and seas.
