I am trying to scientifically prove god's existence. I recently came across a free book that is attempting to do the same and I was wondering if there was any truth to what was being said in the book.

Is it foolish to try to prove God's existence scientifically?
The current scientific method does not, and in many way, CANNOT prove such an existence. The blog you posted makes up random senseless equations that may look scientific if you don't actually read them, but are in actuality crap. Take for example his equation that happiness divided by sadness = 1. How do depressed people fall into that? How can he possibly boil down all of humanity into such a simplistic idea?
The heart of the matter is that god has been used as a catch-all to explain things that are otherwise not explainable. Science seeks to explain things, and so therefore pushes back the boundaries of what societies deem as divine. For example, ancient people believed the sun was god because it was mysterious. We now know what it is and suddenly it's not so holy anymore.
