god, is there one?

is there a god? people theorize that there MAY be one. but there is no REAL proof. if there is, please show me! because I live in a Christian home and I am confused as FUCK. to some this may be one of those no-go-to subjects. but I really don't give a fuck. if there is one there would have to be more, right? he can't be a dying breed.... can he? and no one ever knows all you think, say, and or do. so like lets say there is a 'god' he would have to have more like him, like the roman and greek gods? here's food for thought, say that god is real, why would he send things HE made to hell? mindboggling i'd say. this has had me thinking for many years. I started this trek when I was around 7 or 8. now I am 19. so about 11 or 12 years. the ironic kick- you- in- the- ass thing is that my grandfather is a preacher and I live with him. but I choose NOT to go to church. and he thinks I am a Satanist. I've tried to explain to him and my whole fucking family that I don't sit up in my room worshiping Satan. what religion is right? because I have no damn clue. if I offended anyone I am terribly sorry. but please anyone that reads this and has any input please let me know.
