I was "Christian", at least nominally. Didn't quite believe at 8 and not at all by 10, haven't seen any reason to go back to religion since then. Rather the opposite...
Gen 1-2 definitely didn't happen and were written by two different groups with different religious views using two different creator-god names
Noah's Ark definitely didn't happen, and the story repeats itself all the time because it crushes together the Yahwist's and Elohist's writing in a manner especially suggestive of natural human authorship
New Testament claims that the human lineage is as young as is reported in Gen 2 (Luk 3:38) and has Jesus - presumably the same entity as God - suggest multiple times in two gospels that the great flood was a real event
That's about enough to deconvert already, and it keeps getting worse the deeper you take things
OP, I have perused your comment history and the following is a genuine question to you, and not sarcasm or an insult; I am legitimately curious what you think: do you think God made you born with autism as a punishment?
Had a couple of reports about this comment, but I can see how it might be intended to not breach rule 1 and the authors comment history seems untoxic. I'll let it stand but it's line ball.
