if you don't believe in god or a higher power, then you must think that this world and its creatures are just robots from cause and effect chemical reactions. i suppose this is another way of saying can atheists, and how many are there, believe in free will in a deeper sense than we are free to make choices that are based on cause and effect chemical reactions?
it's not exhaustive proof of God, and is sort of like the complexity argument for God. but i dont know how you can look at humans and think we're just robots. it lacks common sense.
