God has not put us on earth just to love and forgive, i dont know what religion u come from to be quoting this. In fact if we go back to judism, cristianity and islam, there is alot more to it. Baring in mind these are religion of the books, if you unsure what i am talking about then just google it. Everyone has their own level of faith, some like to believe and some dont like to believe, hence your own choice.

Religion is like a guidance for the believers, if you actually follow it. Like helping the poor, respecting people, remembering god, lives of the prophets (Moses, Jesus, etc), importance of obedience to parents, purpose of fasting and praying, not cheating, gambling and alot more.

Without faith you may lead astray and have bad habits hence thats why we need religion.
