Yes but this science was also developed in monasteries from people who also believed in God. Most importantly they didn't only use the scientific method to produce what you see.
Most medicine and even chemical discoveries happened by accident, not because of planned scientific methods. Science should be addressed only when it is "scientific" not when people try to create something.
Indeed the term has been misused a lot and this is exactly why we see so many people confused. Debates are good. they help us learn.
