We agree that to “prove” the existence of “god” we need to first define “god”. I’ll ask the OP to define this god he is seeking proof of, but I’m quite certain that I’ll agree with the OP, that there is no such god. If I’m asked to give my definition of “god” I will not… as I already stated every positive definition is deniable. And then there’s the question of “what do you mean by proof”…? If it’s rock solid certainty you want, then there’s almost nothing but our own existence that we can “prove” to ourselves. For example, we take each other’s consciousness on faith, because we have to; there is no test of its existence. Most scientists in the field believe that consciousness arises from the complex interaction of non-conscious parts (firing neurons). But even IF we can understand the nature of this complexity, we still won’t be able to prove it produces consciousness. Yet, I totally believe that everyone has an inner life, a subjective experience, a sense of self… but I cannot prove that. Sorry to digress, but there's all kinds of stuff we believe but cannot prove, for some... "god" happens to be one of them.
