This next section will be centered on one of evilbible.com's articles that felt to me the most bothersome. On their website they believe they have proved a God cannot existence through the fact that his definition is self-contradicting. I am debunking now what attributes of God they call contradicting one another.
First of all, here's what a universal negative means. A universal negative is an object of which its very definition contradicts what it is, therefore it cannot exist. To use an example, a cubic sphere, because the definition of sphere is a round, no sided, 3D object and the word cubic means to have four sides. When attempting to use this sort of logic to explain the existence of God we must keep one thing in mind. God is infinitely complex in ways that go far beyond our own understanding. "For my thoughts are not your thoughts, neither are my ways your ways" Isaiah 55:8.
