A lesson well learned from Noah.....

[Wyrd of Gawd]

Christians can't even decide if the story is literal or metaphorical. Even after consulting God.

How are we supposed to take any of this seriously?

If I wrote something, and it was meant to be literal, I would tell everyone who asked me that it was literal. I wouldn't tell half the people it was a metaphor. And I wouldn't change my answer as science advanced either.

To be fair, that is what all religions do, even those of Asia and the Orient. When you call out a claim, they move the goal posts, it is also why the religions of Asia and the Orient call it a philosophy, when it is just as much a religion as any other. It allows the follower to cling to the past and still justify old claims even when time and science has passed it by.

In all religions, it is literal until challenged, then the word games are employed in order to adapt so they can stay alive despite the contrary.

All of the major religions are Asian.  This includes Judaism, Christianity, and Islam.
