If we are speaking about the asteroid widely believed to have caused extinction of the dinosaurs, then you ought to take into consideration that the crater left by the impact of that asteroid is the Chicxulub crater. This crater is found off the coast of Mexico near the Yucatan Peninsula. Which raises the following question: if the asteroid believed to have destroyed the dinosaurs in fact was responsible for the destruction of Sodom and Gomorrah . . . why is the crater so far from the Middle East?
I mean, maybe Sodom and Gomorrah were actually cities just off the coast of Mexico . . . having the Israelites in the new world seems to contradict a lot of what we know about history, but if the facts suggest this, then it's clear we really need to redefine a good deal of history.
So what are these facts that make you so certain that this asteroid in fact destroyed Sodom and Gomorrah? I hope you let the scientific and archaeological communities know, as this would obviously completely change our understanding of the world.
