There is not now, nor has there ever been, any proof of any god's existence.<quoted text>
The problem is that people associate God with magic. When they search for evidence of God, they search for magic. They search for something inexplicable, like a miracle. This causes people to unwittingly develop the notion that anything explainable is not from God.
It's like if I build a factory and that factory builds robots, and then I go around in the street telling people that I built the robots, they say "Nonsense, these robots come from the factory!", and they can show me all the trademarks and instruction manuals and even the entire engineering of those robots, and they even take me on a tour of the factory.
But despite whatever explanation people give and how knowledgable they are about how the robots were made, it doesn't remove the fact that I built the factory, I built the machines that build the robots and hence I can certainly assert that I built the robots.
What God has done is far more genius than merely building robots one by one with His hands, as creationism suggests about species. He established a system of physical laws that ultimately created a self sustaining environment for life to not only survive, but self adapt and evolve. And that is why despite discovering evolution through all his research and observation, Darwin did not say that there is no God. While he rejected Christianity, he never became an atheist and never rejected the idea of an all powerful ruler and creator of the universe. At the most extreme, Darwin expressed agnostic views, stating that "the whole subject is beyond the scope of mans intellect".
The point is, all of the explanation as to how a specie came to being, ultimately does not negate the claim that God created the system that resulted in such a species and continues to drive its evolution.
None. Nada. Zilch.
