Ah-ah, now hold on there. Not "dude" - one.

Qarries are the same as trenches apparently. Sea floor spreading and layers of basalt rock and centuries of expansion... clearly that's the conspiracy.
Apparently the deepest quarry is 1.2 km (1200m) while the deepest trench, the Mariana trench, is 200 km deep (200,000 m). Totally the same in scale /s
The rising sea levels in lower Mesopotamia would have been visible on a human timescale. It's not hard to get from "my grandfather lived in a house which is now 100m out to sea" to a mythology that a flood drowned the old world.
Yeah, pretty much this. People like living near water - you can drink it (if it's fresh), you can use it for rudimentary sanitation, you can water animals and crops much easier than building complex irrigation, and you can use it as a food source (fish/shellfish).
(if you're not familiar with the new mudflood/tartaria conspiracy theories, they're wild. people just keep inventing wacky new shit to theorize about.)
I just had the mental image of a scaled up front end loader about the size of Rhode Island pushing an ungodly amount of material around. So thanks for that
