There has long been a debate about how literal to take passages of the bible. For instance, I'm not taking the story of Adam and Eve literally. However, biology tells us humanity did all spring from an Eve, and all one need believe as a Christian is that there were the first humans disobeyed God for it to be true in an allegorical sense. I don't presume to understand it all, nor that there aren't mistakes in the bible, there are.

As for being a former Morman, I get where you're coming from, as I was a lapsed Catholic for a decade or so until I had a spiritual awakening. It's given me the distance to appreciate the myriad problems with the church, let alone Christianity in general.

You see, though, you are taking things from the bible that are similar to things in other religions or cultures, from the time of the writing of parts of the bible, and assuming that the bible copies those things in creating a story, rather than that thing just coming from shared cultural aspects. For instance, Moses is put into a basket and pushed down a river. This thing shows up in other religions, that is, the baby in the basket down the river. But it was also a cultural thing in the region at the time, the same way it was common at one time in America to leave a baby on the rectory doorstep and how firehouses are safe places to drop off babies no questions asked today.
