TSNP:>>But as to "15 cubits above the tallest mountain." The Hebrew in Genesis 7:19 and 20 is tricky. My conclusion is that the 15 cubits IN HEIGHT (there is no Hebrew word of that period for "depth" per se) and the "covered the highest HARIM" [hill or mountain] ARE IN SEPARATE CLAUSES. To put it another way, some translators put a semicolon stop between them.
That makes sense for the fact that Noah would have no means of measuring such a depth of over 29,000 feet. No, he simply observed that the tallest HILLS were covered and the waters of the flood were 15 cubits high. What we can say FOR SURE is that the Hebrew of that passage is hard to be dogmatic about as to the depth of the water.
Dear TSNP, You are correct. Since the waters were NEVER on this Earth, they did not have to be 29k feet deep. They could have been 15 cubits deep and STILL have covered the highest hills of Adam's Earth.
TSNP:>>Of course, judging by today's geologic evidence, there is ZERO evidence for a global flood.
Amen. The Flood destroyed the world of Adam and NOT the present world. Those who look for the Flood here will NEVER be able to find it. The only remnants which could possibly be found, on our Planet, are the remains of the Firmament or the Ark. I would suggest looking for them in Lake Van, in the mountains of Ararat, since a ship 450 feet long would fit better in the largest Lake in the region, instead of on a mountain top.
In Love,
