To me, the biggest objection to believing in God isn't scientific, but moral.

I'm going to borrow from a speech by Christopher Hitchins: It seems painfully obvious that if there is a God, He (for he CERTAINLY is a "he") is cruel, vain, idle, vengeful and sadistic. There is simply NO adequate religious response to the question of why there is as much suffering, hate and like garbage as there is in the world, and any ethical person should agree.
