A PRACTICAL MAN'S PROOF OF GOD

The purpose of this brief study is to offer a logical, practical, pragmatic

proof of the existence of God from a purely scientific perspective.  To do

this, we are assuming that we exist, that there is reality, and that the 
matter of which we are made is real.  If you do not believe that you
exist, 
you have bigger problems than this study will entail and you will have to 
look elsewhere.
