Just as having faith is not a requirement of science, proving the existence of God is not a requirement of faith. In fact, latter can lead to lack of faith if one remains increasingly unsatisfied while proofs become available.
Notice the statement: "I will not believe in God unless I have proof". This statement is actually disingenuous, because the ultimate external proof of God's existence would overcome the belief/disbelief duality thus subjecting the human mind to an undeniable reality that has to be accepted by all. Like the Sun being accepted globally for what it is. Then you would 'know' God, having no choice in the matter (i.e. no belief, no faith). So faithlessness is a choosing of one's own destiny, which is why many people, whether consciously or instinctually, are very careful about it. Simply put, not everyone prefers the prospect of knowing God through lack of choice or being condemned to faithlessness. Some (i.e. gnostics) claim to have known or experienced God; good to understand that the quality of their knowledge springs from their own choice or free will which is available while God is Unseen.
Unless one truly attempts to understand what faith is, great amounts of energy will be wasted by non-scientists assuming the authority of scientists and on the other hand by scientists preaching non-science (I like how this sounds similar to non-sense). I think a level of maturity is lacking overall. Religious persons need to respect the authority that science has and steer away from appearing ignorant. And those who have no faith should appreciate that there are laws and manners governing spiritual progress. They'd be surprised!
Religion should be concerned with perfection of human character and the betterment of our planet through faith as it is a practice after all and not a theory. What religion holds as advantageous is inspiration through "sacrificing, giving, letting go" which is deeply rooted in the concept of faith, because, having faith requires one to deposit trust (i.e. give). That fuels determination. I recognize that this can be abused, however, atomic energy was also abused and it does not mean that because of it we should curb chemistry and physics.
Finally, in response to one of Prof. Dawkins' interviews where he poses the question: since there are many gods according to people's beliefs, how do you know which one is the right one?
The ultimate faith is in one God as this matches what we observe in ourselves and outer space. All existing dimensions and infinity can be summed up as a whole, leading to One. Also, all numbers result from the existence of One. Whether it is within our logic or in the universe we see One as being associated with the primary, essential, basic, central, core and all-encompassing, etc.
Moreover, the ultimate faith is in the Unseen God as that is the only way faith is possible as I have explained above (please note again, the result of faith can be 'knowing/experiencing' God). Other kinds of faith, in material objects, are subject to the scrutiny of science and are therefore inferior. The Unseen aspect is also precisely the reason why God cannot be catalogued with the rest of the scientific discoveries and is impenetrable.
Thank you for taking this brain exercise. Hopefully it helps with your open-mindedness.
Would like to also point out that we are receptor-conveyors of all possible knowledge and experience. None of it originates from us. Neither do our faculties, enabling reasoning result from us. First, let us start from the "temple" of our knowledge, which is the body with all the faculties. Is it a result of our achievement? Our knowledge could not have preceded the formation of the matter resulting in this capable body. Secondly, how did we achieve the ability to organize, classify, calculate, derive meaning or how did we achieve the ability to use this body as a vehicle? I think through observation of the orderly complexities within us and surrounding us and interaction with with all this. Let us steer away from asking the "Who" question, before recognizing first that logically we cannot attribute this to ourselves. That is the humble start for one's faith in God to occur. The rest is left to the person to seek and find. Then, let us not interpret our discoveries as our ability without respecting that it was taught to us, silently, by nature if you will or God. Only then have we achieved a mature state as human beings being truthful about our reality.
