What if God was proven to have never existed?

There is science on one side and on the other side there is philosophy, metaphysics and bullshit.

Have you ever smelt the odor of a measles-infected dinosaur's shit? I suppose it to be totally like what you posted here. Everyday you impress me with your primitive thinking.

Firstly: Philosophy is not separated from science and not all the philosophies are metaphysical. For instance the postmodernism philosophy is related to quantum mechanics.

Secondly: Even for metaphysics... a certain way of a reasonable scientific thinking may lead to put "God" as a probability not equal to zero (for me it is very improbable), because some physicists see that physics laws may be a reflection of an external reality ... Steven Hawking himself said that there may be a "god" who put the laws of nature, but he doesn't intervene to break them.
This point is in which physics ad metaphysics may intersect... but, for me, I had my reasons to dispel the idea of deity to that extent which allows me to describe my self as a strong atheist.
Metaphysical origins of the physics laws are not confined to deities or gods, there are other probabilities such as the thought of that we live in a "fake" world or we live in a "computer" manufactured by other creatures out of our Nature and physics .... They will then be "metaphysical" creatures, but not deities or gods in the popular senses. It is another probability which is not equal to zero, but I have some critiques against it.

I have several times challenged this god of yours to logon and debate me personally. So far no god. And I am certain you god can speak for itself so no excuses or explanations from you.

I don't believe in him. But at all events we should be open-minded to all thoughts even if they appear trivial to us. At least because this is the way to understand others and change them if possible.
