As for ID, creationism or evolution, all are theories imo. All require faith in them.
Newton's theory of gravity actually is a "theory." To the extent people take it as "fact" is in the same sense one may call evolution (also a
theory) a fact.
Gravity is the force of attraction between massive particles due to their mass. Weight is determined by the mass of an object and its location in a
gravitational field. While a great deal is known about the properties of gravity, the ultimate cause of the gravitational force remains an open
General relativity is the most successful theory
of gravitation to date. It postulates
that mass and energy curve
space-time, resulting in the phenomenon known as gravity.
The first mathematical formulation of gravity was published in 1687 by Sir Isaac Newton. His law of universal gravitation was the standard theory
until work by Albert Einstein and others on general relativity. Since calculations in general relativity are complicated, and Newtonian
gravity is sufficiently accurate for most applications, when dealing with weak gravitational fields (i.e., launching rockets, projectiles, pendulums,
etc.), Newton's formulae are generally preferred.
Even laws and "facts" can change. That's why it's science. That's why they're theories.
But it's a straw man to say one must have "faith" in the theory of evolution, just as it would be to demand one have "faith" in the theory of
gravity. Just because I can't prove the hand of God isn't pushing me down instead of the postulate of attractions between mass, doesn't mean I
throw the foundation of modern physics out the window anymore than I do the cornerstone of biology.
