This is nearly the plot of a short story I remember reading - dude's awareness survives death, after a while a voice comes along and informs him that doesn't happen to everyone, and that he was chosen. A while later he realises that an infinity of this boredom is going to shit him to tears, and that the voice is probably God, and the only way out of this is to figure out a way to kill God.
The voice says he shows promise; he figured that out in record time.
There’s a fair amount of evidence indicating that god, contrary to prevailing belief, is not perfect.
It’s also possible that god is tired of existing but is unable to uncreate itself. Perhaps it thinks a transcendent AI could do it.
