Does you're religion believe Moses parted the Red Sea?
I believe that a set of natural circumstances were interpreted as divine intervention because they took place to the advantage of those who prayed for the intervention. Now, that doesn't mean that it wasn't divine authority - and I'm not saying that it was purely coincidental, but Moses did see what was in the "mountain" and he knew how to correctly interpret those signs. Check these records out... they were hijacked and words were added to them (different interpretations), so I'm just going to give you these snippets:
And mount Sinai was altogether on a smoke, because the Lord descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly.
And he showed me a mountain range of fire which burnt day and night.
I came to a river of fire, which flowed like water, and emptied itself into the great sea westwards.
And I saw a burning fire which ran without resting, and paused not from its course day or night but ran regularly.
He divideth the sea with his power, and by his understanding.
Now, you and I know what kind of "mountain" has smoke pouring out of it with "fires that run like water" that pour into the sea. We know the word for it - we call it a volcano. And we know what kind of damage they can cause.
Could a volcanic eruption cause water to become foul and of the color of blood? Yes.
Could a volcanic eruption cause a tsunami? Yes.
Would a tsunami pull a sea back? Yes.
Would it then come crashing back? Yes.
Would it cause other plagues (firey hail and ash, etc)? You bet!
Does this mean it was not divine intervention? No.
Natural events are always divine intervention when their nature is "revealed" and, in the case of Moses, the nature was revealed and he used it to save his people. It doesn't make him clever... it just means he was "aware" and it's that awareness, that I call "divine province". For instance, when you come to a street that has a hundred signs and ads plastered all over it - but only one of them catches your attention... there's a reason for that. Most people don't bother figuring out what that reason might be... but there are some who do. It's an ancient language. I call it, guidance... the same of which brought me here to this very forum, out of the millions that were available to me.
The words:
He divided the sea {snip} by his understanding.
Well, that's my best shot at the interpretation.
