Had obscurantism prevailed, the Earth would still be flat

I originally drew this cartoon with the title: Had Galileo not existed, the Earth would still be flat.
After I posted it, some enlightened readers, rightly pointed out that it's the Egyptians who determined that the Earth was round and calculated its circumference, a few thousand years before Galileo's great grand parents met.
I've learnt a lesson here and should have verified my facts before posting.
