When the water receded, the marine life would continue to go where the water was and would still be alive and thus not mixed with the skeletons. The skeletons could have been broken apart by bull sharks (capable of living in salt and fresh water) and other sharks and also broken up by waves pounding on the shore as the water receded.
What bull sharks? Acording to the Genesis account, Noah had to take seven pairs of every clean animal and every bird, and one pair of
every other creature, to keep their kind alive. God killed everything else apparently, otherwise there would have been no need for Noah to save at least one pair of 'every' creature, so according to the story, at that point in the story, there were just two bull sharks in existence, the ones in Noah's Ark, which must have had some form of fish tank built within it.
The same naturaly goes for any other species you want to blame for eating the remains of all the dead people and creatures after the flood. According to the Biblical account, the only creatures to survive were the ones on Noah's Ark, they couldn't possibly have eaten everything else once they were released, it'd be like me expecting you to eat a cake that's the same size as a skyscraper.
So that leaves an obvious question, where are all the remains of of all the creatures and people that died in the flood? If it happened, there
should be an archeological layer packed full of remains that dates to around '2348 BC'..... because, as I'm sure you're aware, the Masoretic text of the Torah places the 'Great Deluge' as happening '1,656 years after Creation', which, according to the Biblical geneology lists, happened in 4004 BC, giving us a date of 2348 BC for the flood.
The Biblical dating of the flood brings up another puzzling question too. Y'see, historicaly, around that time, the sixth dynasty of Egypt was just starting, and the dynasties of Egypt continued pretty much unbroken up until the thirty-first dynasty of Egypt (343 BC to 332 BC) after which Egypt was handed over to Alexander the Great.
So how could this be? If what the Bible says is true, then the Egyptian Empire should have ended in 2348 BC with the deaths of every person on the planet apart from Noah and his family, so how could the Egyptian Empire have not only continued
through the flood but actualy grown and flourished after it?
The same question can be asked of the Akkadian Empire too, which started in 2340 BC and continued for 160 years until 2180 BC. If everyone apart from Noah and his family were killed in the flood in 2348 BC, then where did all the people who made up the Egyptian and Akkadian Empires suddenly appear from? And why didn't the Egyptians (or the Akkadians) record a global flood happening at the beginning of their sixth dynasty? It's not as if it's something that they wouldn't notice.
Also, come on now, you've been avoiding this question for days now, even though I have
politely asked you for an answer
every day since I first asked it, and to be fair, your avoidence of it isn't doing your credibility any favours whatsoever, so how about
finaly answering that question of 'if the Book of Genesis has been changed from the original scripture,
as you yourself have claimed elsewhere in this thread, and if that original scripture is lost to history, then how can you possibly know that the changed 'copies' that we read today are still a trustable source?'
