The difference between religion and science is that with religion, you must believe what you're being told without any evidence or demonstrable test results, whereas with science, you can actually produce demonstrable results or produce mathematical proofs. If you know that gravity causes acceleration of 9.81m/s², understand aerodynamics, thermodynamics, can measure air density, mass, and thrust, you can cause and object to freefall sideways around the planet. You can't do shit with religion but what you're told like good sheep.
