A small clerical error.
I looked around in bewilderment at all the sunshine and clouds. "Am I in heaven?" The old man sitting across from me at the table smiled benevolently at me. "Why, yes. As a matter of fact, it is. Allow me to introduce myself. I'm God." I could only stare in stunned shocked but he only just chuckled in a good-natured fashion. "Sorry for all this coming out of the blue, but unfortunately, there's been a small issue with your paperwork, just a bit of a clerical error, I'm afraid. It seems that I owe you a bit of a small apology. Allow me to explain..." (Just a silly prompt. Makes a fun springboard for different ideas. Maybe you get isekai'ed, maybe you go back in time, maybe God just sets you up with 100 girlfriends that really, really, really love you.)
