I don’t know if that beam is from Noah’s Ark or not but we have to remember just what the bigger story is here. We’re talking about a rainstorm of truly God-like proportions. If God is truly a “God,” then He/She/It can do anything He/She/It damned well wants to do. If that calls for 14” of rain per hour, then that’s what we’d get. Did that actually happen? I don’t know but I kinda lean toward believing it until someone can give me real proof otherwise. Right now the question is a race between opposing theories and proof is still in the last turn.
Faith in God does not require one to ignore reason and science, nor does it require absolute literal interpretation of the Bible which, after all, was written by man, several hundred years after the events depicted. Science, reason, and Belief do not have to be mutually exclusive.
Was there a flood experienced by Noah? Most likely. Did it inundate the entire globe to a depth of over 13,000 feet? Highly unlikely.
