I believe that Spinozas' work from the 1500s on ethics is a proof on the existance of God but it is not an anthropormorphized concept of God as we think of it. He was a philosopher that believed that things had to be proven mathematically with logical proofs. A concept that i hated geometry for but which lead to his theories to be the basis for much of modern psychology and other writers living after him. His works are not an easy read so it quickly becomes obvious that he was a genius. His works were of course banned by the church but still they survived. They are quite expensive, even on Kindle. Spinoza's metaphysics consists of one thing, substance, and its modifications (modes). Early in The Ethics Spinoza argues that there is only one substance, which is absolutely infinite, self-caused, and eternal. He calls this substance "God", or "Nature". In fact, he takes these two terms to be synonymous (in the Latin the phrase he uses is "Deus sive Natura"). For Spinoza the whole of the natural universe is made of one substance, God, or, what's the same, Nature, and its modifications (modes). This has recently been proven in physics. See the standard model of particle physics above.
