Except the whole ideology behind the flood myth was written about by the Sumerians and inherited by the Babylonians long before they were written in the Bible. Yet the writers of the Bible claimed it as uniquely their own of their own God.
The stories are the same, but which was documented first? And which was so closely mirrored many many years later? If they did not disclose where they got the ideology in the first place then they meant to hide where they sourced that ideology and call it their own.
This is plagiarism. Have either of you ever even read the prior Sumerian/Babylonian flood myth to compare them? The ideology of constructing an ark and a great flood was not uniquely Biblical and it was documented long long before...
But to be fair... The flood myth was more than likely shared by oral tradition from other cultures long before the Sumerians documented it in writing. So even the Sumerians probably plagiarized it too.
“Yet the writers of the Bible claimed it as uniquely their own of their own God.”
Nope. Did not happen. That is not claimed at all. You cannot find a single verse in the Old Testament to that effect. The Biblical writers claimed that the God they revealed was uniquely their own. You need to find another object of your anti-Christain venom. You people amaze me. That statement you just made. You just took ownership of it, but it is certainly not your own. You got it from other sources. That was once common knowledge.
And in the age of exploration during the 1700s and 1800s, explorers discovered isolated cultures that had a flood myth. The American Indians told Buffalo Bill of giants that once roamed the land.
Genesis 6 is hardly explained since it was such common knowledge, across cultures, at that time, except all the other cultures thought it was a great thing, when “gods” walked among men.
