Uh-huh. Where’s the huge crater such a hit would create?
It’s called Hudson Bay.............
supposedly up near Sudbury Ont., and also supposedly responsible for the nickel deposits there.
The huge crater(s) is/are probably in lake Michigan. Sudbury was caused incredibly earlier, I think it might have been at least a billion years ago, but certainly not during any period of humanoids. Sunken Civ, time to post that Firestone book on the 13,000 yo meteor strike.
