Well, if you say science does prove God, then you must already have a clear definition in mind.Science does prove god, though. Just not in the definition and manor in which god is actually defined by both sides. On one side, deities can't be proven by science; and, science isn't the means to prove supernatural beings. On the other side, subjective experiences and personal understandings can't be proven by science because they are personal and no one person's experiences is the same as the other.
Once both sides have the same definition, maybe we could figure out what god is in order to see the OP makes sense according to the definition agreed on.
If science has proven God, it'll be the first thing science has ever proven.
Why, given this proof, aren't we all in perfect religious accord?
