Köfels impact event

The Köfels impact event is a hypothetical incident where a kilometre-long asteroid crashed into the Alps, near Köfels, Austria in the June of 3123 BCE. Upon the asteroid's crash, a ridiculously large amount of plumage rose, blotting out the sun for a few days, and raining debris hundreds of miles away. The Köfels impact has been proposed as a naturalistic explanation for the Israelite story of Sodom and Gomorrah and the Greek story of Phaeton's death. The asteroid's movement has been recorded on a Sumerian cuneiform tablet, one of the earliest known pieces of writing.

Liberapedia isn’t sure about this but at least one University takes it seriously so it looks more reasonable than standard Pseudoscience.
