Maybe. It's a big, weird universe. BUT it also DEPENDS on what you MEAN by "God."
I pray sometimes. It "can't hurt," as they say. In the TV show One Mississippi, comedian Tig Notaro asks a religious woman, "If God LOVES everyone, then why would you need to pray?" and a woman pauses then says, "A parent has love for all of of their children, but they feel a LITTLE closer to the ones that call them once in a while..."
Having said THAT:
1) sometimes I think there's only a "Devil," but not in a typical red, laughing goat-guy way-- just that the universe is trying to torture me, like the A.I. in Ellison's "I Have No Mouth..." short story. Sometimes, I think there's a God but it's THAT,
2) I don't really care that much, re: suicide; I certainly feel like I'd have EVERY right to do it. It's, as they say, MY life,
3) God isn't an author; books are written by people. I don't believe in a Sacred Text. Not a chance. I don't care if the religion is 2 days old, or "Oh, OURS are WRITTEN IN STONE 300000 YEARS AGO, look at ALL these monuments and relics, so they're more trustworthy." To me, they're more UNTRUSTWORTHY, the older they are, irrelevant to the present, and likely to be false.
EVEN IF there is a God, I'm not sure they hear prayers, have the power to give life or "save" a "soul" to make a mortal immortal (that's a PRETTY FREAKING BIG ask of a being, even 1 with magical powers), have exactly TOTAL omnipotence ("Can you make a rock so heavy that you can't lift it?"), or if they even care much about our little corner of an infinite universe. Many people have hubris, and a HIGH regard for mankind's "genius" and "power," so "A God is REALLY hung up on us, because we're 'important," but I find that pretty ridiculous, whether on the surface or seriously thought through. Humans are pretty sordid little faulty animals. We're in "God's image"? Pfffff.
