Only atheists can answer this?

why dont u believe god, how could this universe be made without god and if u say well where did god come from then ur saying he did make this universe. if god didnt exist then how do u explain exorcisms and jesus, moses and mohammed. there is no reason to be an atheist because if u dont believe god and ur a good person u go to hell if u do believe god and ur a good person u might go to heaven. please believe
