Is there something wrong with me if I believe in God?

There is certainly nothing wrong with you just because you believe in a deity. This kind of belief has been part of human culture for as long as it has existed, no matter what your beliefs are concerning origins of the world and of life. Go as deeply into the world of your faith and belief as you can, if that is your desire. On the other hand, there is certainly nothing wrong with wondering about and questioning your beliefs, and going fearlessly wherever your explorations lead you, short of doing anything that could hurt others or yourself. If faith is real, and if you have it, questioning and exploring can only leave you stronger.
