This is true, but theories lead to hypotheses, which then lead to objective studies, which then leads to empirical data....this means that the theory LEADS to evidence.  The theory is NOT evidence itself, and the theory may change due to the outcome of the empirical data...on this note, the data did NOT change the theory of evolution, thus the theory was PROVEN by the data.  The use of the word "theory" by biologists is tantamount to the use of the word "law" by physicists.  Just because the "lay"definition of theory means idea, that does not mean that "scientific" theories are just ideas.  I am not trying to bash anyone in particular, but the "theory of evolution" often gets passed off as a theory that is still just an idea.  If you look at history, the first person to think of evolution wasn't Darwin.  Lamarckian evolution was wrong.  He had a different idea of how things evolved which was wrong...thus we no longer view "Lamarckian" theory as the proper definition of evolution.  Natural selection does not equal artificial selection, and that does not mean that we evolve for a purpose.  The big picture does not have a purpose, and humans in our infinite search for purpose want to impose our own self-importance onto the universe.  I hate to say it, but we are nothing in the giant cosmos, and if god were real, apparrently she stopped giving a shit about us a long time ago...

Just another way of saying that a theory is just a belief system. Doesn't matter how you arrive at your conclusions it's a theory. A belief based ultimately on the unknowable, and as information is accumulated and disproved what was once taken as "law", is replaced by another speculative "theory" to explain it.

In the study of the universe a known, known suddenly becomes a known unknown because a simple observation of a phenomenon not expected around a black hole or other event doesn't meet the expected results.

The theory of evolution has undergone numerous corrections in the years since it was first purposed. Arguments still abound. All based on a belief system, each scientist confident that their "theory" is correct.

The "laws" of nature change routinely as "science" explores the cosmos and discovers what once was "believed" to be a trueism doesn't apply in a particular instance and "science" can't agree. 

Most science contradicts itself the more you study the cosmos.

Simple question, can matter/energy be destroyed?

See Hawkins paradox.

There is more in the universe we don't understand than things we do yet many will eliminate the possibility of a higher intelligence, because it's not yet an observable event.

I will state again, I'm a science kind of guy, but at least I understand that even science doesn't really understand the universe, it only develops more "theories" to explain what is currently observable.

In the scientific world, it's the other way around.  The scientific method, without which there can be no science, is pretty clear about this.  Sure, in the layman's world, "theory" means the same as "hypothesis", but lay people don't have to be as precise as scientists.

The scientific method is a very specific logical procedure used for learning what is true and what is not.  Some science is based on empirical evidence.  Other science is based on logical proofs.  There are many other types of evidence that can be used to support a theory, but theories are developed by testing hypotheses.

If a hypothesis is shown to be false in all circumstances then a truth has been discovered that may be used to develop a related theory or prove a fact.  If the hypotheses proves to be true in one or some circumstances but is unproven and not disproven in all other circumstances, then it's a theory.  If it can be proven true in all circumstances, then it's considered to be a fact.  Other test results are usually judged to be inconclusive.

In any case, whether a hypothesis are proven true or false, the tests can be said to have been successful if any result is obtained.

In addition, "theories" and "laws" are different.  A "law" is true in all circumstances in a given universe.  A theory does not yet have that distinction.

Rigorous empirical studies and experiments show that evolution occurs.  Scientists argue about some of its exact mechanisms, but not about its existence.

Only religionists, who are not scientists and who are not qualified to judge scientific matters and who in fact eschew all logic, argue against the existence of evolution.
