Scientist always (have to) concede, that there are phenomena that science cannot explain - yet.
Scientifically there is no way (not yet?) to prove that there is an almighty being. There is also no way of proving that there is none - scientifically its an open issue.
Philosophies fill a gap - because there is a human need to understand, and a distinct discomfort about something "unexplained".
Eventually they will be proven or disproven - and in the meantime, argued! <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
