And now, for a very short rant on what science isn't, and what it is....
Science is not a set of beliefs, it is a system for finding out about the world.
What you think of as science, the body of knowlege, are all the things other people found out about the world by using the scientific method.
The beauty of science is that you don't have to take anyone's word for it. If you doubt something that someone else came up with, you can apply the scientific method to find out for your self whether or not it is true.
Nature is there, ready to answer our questions. We just have to phrase them correctly.
Update: I recently read a Reddit post by HeroicLife with a similar take on it. I like the brevity of their initial statement:
"Science is knowledge that can be verified by anyone."
They went on to say:
"Science is free from dependence on emotional states, hearsay, divine revelations, cult secrets, holy books, or cultural knowledge. Anyone with the right tools and an active mind can establish and verify scientific claims."
