Indeed, in fact the entire science of quantum mechanics is based upon such tests. Furthermore that atoms are a theory means nothing, the entire science is a theory, evolution is a theory, black holes are theories.the·o·ry a coherent group of general propositions used as principles of explanation for a class of phenomena: Einstein's theory of relativity. That is what science does it finds a theory that explains what we see.Now God is not needed to explain anything in science (he was needed, up until a few hundred years ago), apart from the origin of the universe, the big bang, this is the most commonly used proof of God in science, however science stops where the universe ends, so the question of the creation of the universe is thus regarded as pointless (there are however scientific theories, but since they cannot be proven no-one really accepts them, these theories are such as the big bounce theorie or the theorie that the universe was created from a quantum fluctuation that caused virtual parts to become real in a chain reaction).Now the claim that we are too complex to come from randomness is one that has been made numerous times, however if you read for example 'the web of life', by Fritjof Capra, you can see a good explenation on the mechanisms that have created us. The whole hypothesis becomes much more convincing.However the theory of evolution, when we look at it logically, combined with the claim from science that laws of nature are universal brings us some scary implications.If laws of nature are universal, than a particle in your brain will not act different than a particle in a rock: every motion can be described in terms of formulas.This implicates that human behavious, can be described in terms of very complex formulas. And therefore that any free will, any intelligence, is caused by laws of nature, and therefore that free will and thought are simply illusions from these laws of nature.So we are nothing more than pure complexity, or in other words, we are nothing more than a complex rock. The illusion of thought will vanish when the processes in our mind stop.And this is exactly why Chrisitianity and Science cannot co-exist on a fundamental basis, they imply completely different things.Now for the prove of God, I have said in another topic that God is beyond our sight, and therefore we cannot disprove God, however it is possible to prove God.If a miracle would occur, which is impossible to explain through science, it would have to be an outside force, outside of reality, this still wouldn't tell us anything about the nature of this outside force, but it could be very likely a god,.
