those of us in the judeo-christian, biblical creationist tradition, feel that much of this supposed ‘amazing’ ancient technology, is simply the result of the dispersal at the tower of babel, into the various groups that became ancient civlizations.
These groups of people had the knowledge of this technology as part of the ‘original creation’ that God had given humans, handed down over the eons, but once dispersed and with the languages mixed, the tech abilities were bit by bit, lost.
so what we see in these ancient amazing abilities of these people is simply the usage of their original knowledge, which again, became lost down thru the ages as time passed and groups dispersed ever further.
So how did they pick up and move 100 and 200 ton stones?
There are those who think the account in Genesis 6, of fallen angels mating with human females and producing giants up to 12 and 15 feet tall, who possessed superhuman intelligence and technical knowledge. Google: “genesis 6 nephalim”.
