National Geographic recently reported that 10' feet of silt had been deposited in the delta of the Persian Gulf, which came from flooding that took place, and was carried by the Tigris & Euphrates Rivers of Mesopotamia, appx. 6700 years ago...
The cause of this flooding, was from the end of the last Ice Age, glaciers melted, and filled the Black Sea to overflowing, subsequently, the springs in the Taurus Mountains where the Tigris & Euphrates originate, swelled to mammoth proportions, and when the water arrived onto the FLAT, fertile crescent, everything was wiped out, for at least generation!
Though the flood was localized (Not worldwide), Mesopotamia is where the Old Testament was written, so in essence, it was the "Whole World" to them!
This is also where the early semites (Proto-Jews) and Sumerians (Shinar, in Genesis) rebuilt their civilization, 6500 years ago. That would be 500-700 years before the Fundamentalist date of Creation (which is 4004 BCE).
I would think that's kind of odd, to have verified & documented Bibical archaeology taking place, nearly one millenium before the earth itself was "Created", so I would suggest taking at least a junior college-level science class, after you're finished with Sunday School!
As far as seashells on Mt. Everest, that would indicate to a scientist, that the earth's age is hundreds of millions of years old, unless of course, some ocean-faring birds dropped them off more recently, and since Edmund Hillary was the first to climb to the top of Everest, 50+ years ago, there have been over 100 successful expeditions to its summit. Contamination of the site is equally possible!
With wild conclusions like you've made, I could see why you'd never make it as a forensic detective, or anthropologist!
P.S. If both of our polar caps melted in their entirety, ocean levels would rise a grand total of 244'. Mt. Everest is over 29,000'+.
Ummm.....where did all this water come from, and where did it go?
Can you explain that?
