What if you have a 1.4 million year old crater whose sidewall loose material only made its way from the sidewalls into the crater lake once, and that was about 4500 years ago.
I, and several others, went into some detail exposing this lie.
Don't you remember what the data suggested?
It was also demonstrated, about the same time, that the side was was not damaged by a flood, but rather likely by an earth quake.
Followers of the Father of Lies apparently have short memories.
