According to the Sumerian texts found carved on the Babylonian wall, we were genetically engineered by aliens who needed gold mine workers. The texts were written 2000 years before the Bible, yet parallel the Bible stories, even with similar names of characters, except that their stories make more sense.

Why was the Hebrew God so blood-thirsty and cruel? The parallel Sumerian texts say the leader of the "gods" was Anu, of the royal white Dracos, and they ate human flesh and drank blood, so required sacrifices from their human slaves.
Why did the Noah's Ark flood happen? The Sumerian texts say that they knew a planet was going to come close enough to earth to break off an underwater ice shelf and flood a third of the planet, so Anu commanded his minions to withdraw a ways in their spaceships and let the slaves drown.

But two of the gods, the ones who genetically engineered the humans, showed their favorite human how to build a submarine, and stored the animal DNA on it, since they'd also genetically engineered the domestic animals. Anu was angry with them, but allowed it.

To me, that made more sense than the ridiculous idea that somehow animals from all over the globe managed to reach one place and all fit in a 150 ft long boat.
