That is correct. God is an idea that man created.
Presuming that that argument falsifies an omnipotent God depends on wrong presuppositions about God and wrong use of the definition of *omnipotent*.
Omnipotent is pretty self explanatory, hard to get that definition wrong.
If you want to disprove God, you're going to have to find a better method than one devised by the finite and imperfect minds of man.
Falsifying the idea of God is trivial. If I look in the bottom of my coffee cup and don't see God I have falsified it. On the other hand you have your work cut out for you if you want to prove the existence of God. Good luck : )
That darned coffee cup of yours again. You've been looking for God in there for many years, on FR alone.
Are you expecting the grounds in the bottom to self-organize into an image of Jesus or something? Maybe a little tiny Jesus walking across the surface of your coffee? What, exactly, is it that would convince you of the existence of God, in your coffee cup?
That is correct. God is an idea that man created.
First you agree that He is not an idea, then you say He is. Which is it? Is He an idea or not?
Then you shouldn't have any problem distinguishing the difference between having unlimited power and being able to *do everything*, as if having power makes one able to do contradictory things, which it doesn't. Starting with a false premise leads to erroneous conclusions. God is not capable of doing *whatever He wants* which is really a inadequate man-made construct.
God cannot change and God cannot lie, to start with, so the premise that God can do everything, or anything He wants, is false, therefore any conclusions based on that will be wrong.
Time for you to head back to Logic 101
Disproving God takes more that corrupted reasoning. In order for you to definitively demonstrate that there is no God, you need to know all things for all time and eternity, and everywhere, which would make you God. Since you can't do that, and aren't that knowledgeable, you by, default cannot disprove God.
