if believe that things around you exist, then God exists. Who is the creator? And if you think that there is no creator of these things, then use all your power and create a single thing. ( I don't mean transform.)

If God prevents all evils, then certainly you should not be rewarded after your life. A person who believes in God believes in life after death, a life which never ends. And Surely, all Unrighteous will be sent to hell.

If God doesn't exist, then who is the creator? will you say the natural forces? Natural laws?... who made these natural laws? Everything has a creator, and the Creator is "God".
