Your own definition of theory says: A theory in technical use is a more or less verified or established explanation accounting for known facts or phenomena. How is God not an established explanation for the known fact that the universe exists? Your definition also defines hypothesis as:A hypothesis is a conjecture put forth as a possible explanation of phenomena or relations, which serves as a basis of argument or experimentation to reach the truth. How is the existence of God not a conjecture put forth as a possible explanation of the existence of the universe which serves as a basis of argument to reach the truth? God squarely fits into both definitions as a theory and hypothesis. If you want to excluse God from both, you need to do a little more explaining.
