A fanciful theory of astronomy credits the Babylonians with witnessing a planetary fender-bender, in which two planets collided, destroying one (Tiamat) and sending the other off into interstellar space (Marduk).

The Babylonians then supposedly incorporated this extraterrestrial event into their mythology.

Like the Loch Ness Monster and the survival of carcharocles megalodon, this is considered crap by mainstream scientists.
