Why do you not believe in God?

[Mystic]

I don't think 'objective greatness' makes any sense because 'great' is an entirely subjective term. There are several questions which need answers:

♥ How do we objectively define 'great'?
♥ What is the base unit of greatness?
♥ Why this unit as opposed to any hypothetical other?
♥ How can I objectively measure greatness?

I don't know the answer to these questions, but I also think they are loaded questions. 1st one is assuming we have to be able to define it rigorously to have a concept of it. 2 is assuming there is a base unit to it. The 3rd is assuming along with there is a base unit to it, that there can be other hypothetical ones. Depending what you mean by measure, this can be a loaded question. I will await what you mean by measure it.

♥ How does greatness prove the existence of ultimate greatness?

This is what I argued for.

♥ If there is an ultimate greatness, how do you prove that it is Yahweh as opposed to any other deity with a similar claim?

I don't believe in religion nor believe in God as presented by Judaism, Christianity or Islam is reflective of the True God.
