When people talk about 'god', they mean a personal god, a deity that can be related to as a person.
From an evolutionary point of view this is a ludicrous idea.
There is as much reason to believe in a deity who can be related to as a person as there is to believe in a deity that can be related to as a whale, a dinosaurus,, a pakicetus, oak tree...
You just need to understand evolution to know there is no god. An impersonal force on the other hand can't be proven or disproven....atm.
Mathematics is a language of logic. If anyone claims a calculation proves the existence of god, then he just shows he thinks it's logic for there to be a god.
