Science with all its faults is the best tool we have to make sense of ourselves and the world around us. But you should know it is not omnipotent and there are things beyond its reach. And is there where most people fail to understand and start endless discussions like the ones on this thread. Science and religion are not mutually exclusive, in fact they can both co-exist as long as you don't mix them. Science is the realm of proofs, evidence,facts, logic and scientific inquiry. Religion/spirituality on the other hand is the realm of claims,dogmas, believes and faith.
You can't (and should not) explain natural phenomena with religion; that's what a charlatan do. For instance, hundreds of years ago people thought that demons and other otherworldly beings were responsible for things they were not able to understand like someone dying because of a little open cut or a person with strange visions and talking in other tongues. Today we know that bacteria and mental diseases like schizophrenia are a more reasonable explanation for these things. In the same train of though it is wrong to try to demonstrate things that are subjective, non repeatable and lack of any verifiable support. That is pseudoscience.
The sole idea of trying to demonstrate the existence of god with proofs and evidence is just wrong. Radi you are wrong not because you believe in higher beings and want to have other explanations, but because you are using the terms facts, supporting evidence and god in the same phrase.
