I would say that Cain and Abel were born after the fall as they had a sin nature otherwise, they would not have been offering sacrifices nor would Cain have murdered Abel.

I agree, plus there is not mention of their expulsion.

The only possible timeline is that Adam was 130 when Seth was born and that was certainly after Abel was killed.

There is some doubt about the amount of time in the garden and whether time as we count it, began at the fall or not.

It’s really irrelevant, however. The speculation is pretty pointless, IMO.

What we have to deal with is the consequences of it and that’s enough to keep one plenty busy.
