Existence of god is a question that all scientists wanted to answer. Since they are belong to a religion and they grow up with a background which lead them to think about the existence of god. Explanations for existence of god lead to many arguments. Main argument is that, is there only one god or existence of several gods. As a person with a Buddhist background I believe that there are many gods. And I reject the concept of ultimate creator.
According to my understandings I think term god is use to explain a high energy stream where as this energy came from a human. That mean god must be a human in his early stage or before he become a god. We all know that all human beings are mad up of organic molecules which we known as physical body.
