The difference is a religious belief is based on "blind" faith and a believer will not change that belief no matter what evidence that may be brought out contrary to that belief. Science is based on theories or beliefs back by observation and experimentation. If that theory by observation is proved wrong it is replaced by another theory.
I recall my grandmother telling me bible stories when I was 5 years old and thinking it was a bunch of BS. At 5 years old I had enough intelligence to know it was a load of crap but it was always explained away that you just believed it because it was "Gods" word. Anyway I would rather believe in something I can prove than a book full of myths, legends and superstitions.
