All what science is, in my opinion, is one of the ways the human minds tries to make sense of this world. Art and philosophy are two other ways.
In the case of science, the human mind has stumbed upon facts, such as "the Earth is round" and "the Earth orbits the sun". Stuff like Classical Mechanics, Quantum Mechanics...etc. are not nessecerly facts but they do make sense of things. Maybe sooner or later another scientific revolution will come and change everything. But the Earth will still be round
