You are missing the point. Most cultures invent deities to explain such things as you describe, and yet they each describe different gods and mythologies, the Hebrews (and later, Christians) included. If every culture spontaneously had the same deity, that might be an argument for a specific outside agency. But instead they all create deities which reflect their own values.<quoted text>Nature is why many spontaneously believe in God.
To see nature the universe and people and spontaneously believe it all happened on it's own, is to be indoctrinated by others and is a made up irrational mental concept.
My conclusion: religion is just projection, and humans have a tendency to be irrational and believe in supernatural forces. It's part of our psychological make-up. All of us fall into magical thinking in one way or other.
