see, i don't see anything particularly infeasible about early civilizations being flooded, but it's not necessary to go as far back as the ice age to get a flood scenario. the neolithic revolution, itself, would have lead to circumstances similar to what we're seeing today as "global warming". you just need to take your timeline forward a few thousand years to make it consistent with everything else. then, you'd have early neolithic sites being drowned as a consequence of the neolithic revolution itself.

the thing is that it's going to be difficult to separate the anthropogenic aspect from the natural one because they would have happened in quick sequence. but note that oceans continued to rise until ~6000 bce - well after the technical end of the last ice age. if you take it up to that point, it's no longer an outlandish date for early advanced settlements.

of course, the creepy thing about this is that all your data is centralized on google's servers, for surveillance and algorithmic analysis to create "personalized advertisements". it's total spyware. that is why google is making these things. apple seems to be moving to a similar data collection model, with it's new portless devices. the goal here is to push personal storage to obsolescence, and make cloud storage the default.

it's a win-win for the intelligence-industrial complex. who needs warrants in a driveless future, where everything is stored in the cloud with not-so-secret backdoors? and, imagine the possibilities of forced ad consumption when google controls your actual internet access.

"error. you have not watched the ad. please watch the ad and then continue."

actually, we need an orwellian term for ad.

"informational video". yeah...
