Don't you mean to say, there is no objective evidence against the existence of my diety.
I'm not going to even try to convince you by discussing the issue about evidence of non-existence of things you assert. That's clearly a waste of my time.
However, moving away from hard "evidence", I wonder if you think there is anything odd or lacking in credibility in the following story?
Immediately after the Flood, the only humans alive on the planet were Noah's family members, correct?
So every human alive was aware of Noah, the Flood and particularly of Yahweh's ability to exact vengeance upon humans who were evil, corrupt etc.
Would you agree that the survivors were rather likely to have found the events to be "memorable", to say the least? Also, is it probable that they all believed in Yahweh? For the moment, I'll assume that the answers are Yes and Yes.
The descendants of Noah were ultimately to spread across the planet, presumably taking their beliefs and family history with them.
Here is where things become just a little strange. The vast majority of Noah's descendants managed to completely forget Noah, the Flood and even Yahweh, with one tiny exception. That is people near where Noah lived. Not one other tribal pocket passed on this knowledge to their descendants. Not in Australia, Polynesia, New Guinea, South America, Lapland, South Africa, North America, China, Japan, Indonesia and so on to name a few. What could have caused this global amnesia? Except of course, incredibly coincidentally, in the tiny geography which gave birth to belief in Yahweh. Most of the world abandoned Yahweh, and came up with other religions. Why did the Yahweh story lack any real durability?
Of all the places where Noah's descendants settled, what are the chances that the only place where Yahweh survived was exactly the same place where Yahweh first emerged. Noah's descendants were all confronted with signs of the devastation which must have resulted from the land being submerged for about a year, yet they forgot the Flood?
Right now, I'm not going to claim that this is "evidence" that the Flood story was a human invention, but I'm smelling a smoking gun.
Then we move on to the more modern question, which is this. If parts of the Bible are not literally true, then we have no way of distinguishing true passages from invented passages, which calls into question the whole Christianity thing.
@SuperCobraJet, what's your opinion on the above? Does your God explain why almost all of humanity was ready to forsake belief and even all memory of Yahweh so soon after Yahweh's demonstration of how he treats non-believers?
