For this discussion, we must first prove there is God and what's God's role?
And if we are already assuming that God exists, we need to prove God's role for mankind (set rules, restrictions, etc)?
And if we are already assuming God's role is to keep peace and harmony among mankind, then we must prove why God's isn't doing it's job correctly?
And if we are already assuming that God isn't doing it's job correctly, then we need to prove who's next in line for that role and whom does the responsibility falls on? Humans?
Now tell me on which above assumption are we going to continue this debate ...
