If there is/was one. Surely it’s got to be something. I have no idea. Should be easier to answer than where did God get his education.
Flesh and blood? Pure energy? Pure thought? Some exotic matter that exists between the elements of our Periodic Table in another universe or dimension? Nuts and bolts as a machine? Geometry equations/dimensions? Nothingness? Quantum particles? Life should it actually be something tangible, not the life form? Something we cannot comprehend (my choice for number one consensus)?
Any of those likely to have a chance of being true? Are there other theories?
