I've had another look at the opening post of this thread and, while it does seem a bit garbled, it seems to be suggesting that the number of detected large strikes occurring over 6-10K years would have wiped out humanity. I have to say that this does make sense, since humanity would have been "in at the beginning" so to speak if we take the Genesis version of creation literally.
Faith, you're proposing an even more extreme scenario - that all of the mega strikes happened in a single year!!! To back this up you're going to have to tackle the physics of meteorite strikes of this magnitude and that doesn't belong in the faith section, it belongs in the science section. You can't just take the flood as a "given" - its up to you to provide evidence that numerous huge meteorite strikes in water wouldn't have par-boiled Noah and his floating menagerie.
I'm enjoying the science in this thread so far and I would hate to see it disappear into faith section where the science stops and the wild guessing begins.
