The question is interesting, because it tells us why people really believe in God. It is not so much because God explains anything, although atheistic arguments usually attack that aspect of religion. It is because God has something to offer us. Atheism promises us nothing--no afterlife, no miracles, no settling of scores. People can pray to God, but atheism takes that away. So I would not argue against the existence of God on the grounds that I would prefer to have no afterlife or for there to be no justice in the universe. For the vast majority of believers, God offers real hope that our circumstances will ultimately be better than they now appear to be.
What drives my atheism is not that I want to see hope dashed for myself and others. It is the desire to make sense of my life and the universe while I still have time to enjoy it. If I could have a real Santa Claus for Christmas, that would be wonderful, too. But ultimately, I need to know where those Christmas presents really come from if I expect to continue receiving them. Because I do not believe in Santa Claus, I know that I must also give presents in order to receive them. I also know that I must work hard in order to be able to afford to give presents. Religious belief helps us cope with life's difficulties, but it can also become one of life's difficulties.
