First of all, Christians have an age of accountability too. God says he is love. He judges fairly. He doesn't care what the kid is like. Maybe he is a devil worshipper until he is around seven. (that isnt the real age. God doesnt set an age, because different perople have different abilities and circumstances to where they can hear about God) That baby would certainly go to God in Heaven to the place He has prepared for him. Second, I would like evidence that we have DNA 97% like that of monkeys.
Third, God lets us make ur own decisions. If we would come down and stop us from fighting then who's not to say he wouldn't come down here and make us all worship him. He would just be the puppeteer. Would you like it that way?
