1) God as we understand Him is a Being than which no greater being can be conceived.
2) A being that exists in reality is greater than a being that exists only in the mind.
3) Therefore, we can't be imagining God.
4) It's inconceivable that there could be a being Greater than the Greatest Real Being.
5) Therefore, The Greatest Real Being is one and the same as the Greatest Conceivable Being.
6) Therefore, God exists.
And don't pretend you don't know what we mean by greatness, "Almighty" you jackasses.
The past finitude of the Universe is evidence that the First Cause exists.
The First Cause is UNCAUSED, Self-Motivated, and Self Eternal.
The only thing we know which can be self-motivated is a Free Moral Agent.
Therefore the First Cause is a Mind.
Therefore God is the First Cause.
The moral argument for God's existence stems from objective Truth and Morality, which are fundamental precepts of Science. You can't do science without an absolute definition of Truth and Goodness. For that matter, this computer does not run without an absolute definition of Truth and Goodness.
Because Objective Morality exists (Murder is wrong) that leads to the question "Where did morality come from?"
The answer is morality came from the First Cause, and therefore the First Cause is a Moral Agent, not just a Free Will. Therefore God is Good.
Anything capable of Creating all of reality (the first cause) is necessarily Almighty.
