The trouble is you confuse popular definitions with scientific ones. A scientific theory is something that tries to explain known observations about the world through a coherent framework. Evolution in this sense is both a fact and a theory. We know that species change, appear and disappear; this is amply demonstrated in the geological record. It has also been observed in nature and in the laboratory. However, the theory part of evolution tries to describe the mechanisms that govern how species change and why. Findings that would be consistent with a young Earth however simply aren't there. Straightforward observational science in astronomy, geology, etc falsify the idea that the Earth is very young.
You also assert that evolution hasn't been proven by science. This is true, but science isn't in the business of proving things, instead progress is made by disproving them. A scientific theory doesn't just explain the facts, it makes predictions that can be put to the test. For example, in the 19th century electromagnetic waves were thought by some to propagate through some kind of ether. However, as any physics textbook will tell you, this theory was falsified by the Michelson-Morley experiment, and the theory had to be abandoned. When Einstein developed his theory of relativity, it too made predictions, and these predicitons have since been tested thoroughly. The other aspect of a theory is that it is open to revision. If new facts emerge that throw doubt on parts of the theory, you have to figure out where you went wrong and change it. If the evidence completely contradicts your understanding, then you probably have to start from scratch.
I'll continue some more in another post...
The scientific method," Thomas Henry Huxley once wrote, "is nothing but the normal working of the human mind." That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes. Taking this point of view, we may conclude that science is not physics, biology, or chemistry—is not even a "subject"—but a moral imperative drawn from a larger narrative whose purpose is to give perspective, balance, and humility to learning.

Anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that my ignorance is just as good as your knowledge
