Ok, God exists. So what? No. God doesn't exist - you would benefit from using the term 'natural forces involved in the big bang and vessel-selection-process.'
Words are an abstraction of reality; to name 'natural forces involved in the vessel-selection-process', God, is firstly, an abstraction of the reality of these forces, and finally, inaccurate therefore.
It seems, people who have no answers, use God, for no other answer exists for our reference; not to mention it refers to a holy book, but given you're implying God is the dictionary definition, we'll skip the theatrics...
You can theorize all day different definitions for God, such as 'the multi-verse', 'light', 'the status quo', but these aren't the definition of God, that is 'deity' or 'higher power'.
'The status quo' exists, we can sense it; why would you reduce the status quo, named accurately, to God? Then you will use this knowledge immaturely, by going to church, rather than helping/hindering the status quo?
At most, the word is useful when defined as 'pointer to forces that we currently do not know about until further notice...'
Can your mind grow out of God, and actually define the higher forces in question? If not, please stop redefining God as you please, it's silly use of words technology.
