And keeping all those animals alive on the ark.
What a hoot that claim is!
Theists could argue that all of the details of the Noah's Ark story are miracles of God.
Miracles:
1. Animals went two by two
2. Animals didn't eat each other
3. There was enough food for 40 days for all those animals
4. The ark was big enough to store all those animals.
5. Noah talked with God (and God talked back).
6. There was so much water in the atmosphere that the entire earth flooded.
My theist friend asserts that it ws an alien spaceship (most likely from Venus, because stars would be too far away, and the climate of Venus was different long ago), and that spaceship wasn't carrying animals, but carrying animal DNA, which was reconstituted into live animals again. Evidence of life on Venus, she claims, was obscurred by the roiled soil of Venus due to winds and meteors.
