The search for God is not an external search.
The search for God is an internal search.
Ultimately the search for God is the search for self, because after all, how could we possibly know the eternal, if we don't know anything about the mortal.
The understanding that there is no tangible proof for God should be put to rest.
This is a spiritual journey not an archeological journey.
The proof for God is found within, not in a book or any of science's experiments.
Science is only able to hint at the possibility that there may be some underlying, unifying field that connects everything and is the source of the material universe.
Science does not have the tools to do much more than that.
The science of the mind uses different tools.
