Why did god allow people to be born after the fall ?

[John V]

By that interpretation we don't exist as autonomous beings with rights.

I agree.  By way of your god we aren't autonomous, which is one reason (of many) why I don't subscribe to any of the religious narratives.  I mean, did I misrepresent your god in some way?  Is my description not accurate?

Point is that if our every thought was in effect prewritten by god, we don't exist in any meaningful sense. We're just characters in a complex novel.
