The Tower of Babel

[Redbeard The Pink]

The tower was constructed of baked mud brick and tar... Not 400 ton granite blocks.
A baked brick means something that is small enough to fit into and not crack when baked... So about the size of the bricks we use now.

bricks are far easier to repurpose than 400 ton granite blocks.

 After all according to you even the great stone henge was repurposed all except the stuff too heavy to move/move very far. with this in mind what in your estimation should be left at the tower site that was made up of hand size bricks??

Not much, maybe. Foundations. Evidence of work crews living/being nearby. Other structures built out of the repurposed bricks. Maybe not much, but something. The same kind of evidence we find near the Pyramids, probably. Certainly more than you've offered here. "It could have happened this way," without evidence, is nothing more than a guess, regardless of how reasonable your ad hoc assumptions might be.
