This is just my opinion. Say what you think about this using the comments.

There are many many religions in the world and we are all part of a religion (or not). But, whatever the religion we are in, we all have a single GOD. A GOD who created atoms to the biggest mammal in Earth. All religions are just a path to GOD. Every religion points to GOD and whatever religion we choose, we all reach a single place. So, if GOD created all the things in universe, then he / she may have created the religions.
