Do you ever look back and wonder "what if"?
Sure, sometimes. Most people do.
What if the god of the bible is real?
If he/she/it is, it ain't a god worth worshipping IMO. Like most gods, they are a reflection of the writer and/or religious beliefs of the time.
What if there is a creator who is not the god of the bible?
Slightly more appealing but just as unlikely for the same reasons.
No afterlife? Did you have to get over this fact or was it pretty easy for you?
It was pretty easy to accept my mortality actually. Carpe diem.
