Humans may not have consciously known that incest was bad, but evolution made us think so before we were even humans. All animals avoid incest, not just humans. We only created those laws and customs because evolution already made us believe that incest is bad. It’s pre-programmed in us, so to speak.
Those laws and customs predates knowledge of genetics significantly.

That isn’t even remotely true.
