Why is the theory of evolution...still considered a theory?

I guess a theory could best be explained as an explanation of facts. Not in competition with those facts. We read and discuss scientific theories a lot in everyday life, but I hadn't really picked apart the term before, and made sense of it. Appreciate everyone's input on this.

Just keep in mind the following distinctions.

Hypothesis:
A hypothesis is a reasonable guess based on what you know or observe. Hypotheses (plural of hypothesis) are proven and disproven all of the time. Hypotheses play a strong role in the scientific method where you formulate a question, create a hypothesis, make a testable prediction, test, and then analyze the data. Even then, a hypothesis needs to be tested and retested many times before it is generally accepted in the scientific community as being true.

Theory:
A scientific theory consists of one or more hypotheses that have been supported with repeated testing. Theories are one of the pinnacles of science and are widely accepted in the scientific community as being true. To remain a theory, it must never be shown to be wrong; if it is, the theory is disproven (this also happens). Theories can also evolve. This means the old theory wasn’t wrong, but it wasn’t complete either.

Law:
Scientific laws are short, sweet, and always true. Many times laws are expressed in a single expression. Laws cannot ever be shown to be wrong (that is why there are many theories and few laws). Laws are accepted as being universal and are the cornerstones of science. If a law were ever to be shown false, then any science built on that law would also be wrong; then the domino effect would have a new (and devastating) meaning. Laws generally rely on a concise mathematical equation.

Not sure if this is a silly question, but since we know that there exists plenty of viable information to support the theory of evolution, why is it still only considered a theory?
Because in the sciences "theory" means a framework in which empirical research can be conducted, experiments designed and interpreted, and data/results structured. The "theory" of evolution is a framework that forms the basis for entire fields of scientific research (e.g., evolutionary psychology) and guides and structures research in a vast number of fields (e.g., machine learning, linguistics, astrobiology, etc.). In the sciences, many theories are more fundamental than entire scientific fields, and evolutionary theory is one such example.

Why isn't it a law?
In general, the use of "laws" to describe findings in the sciences has been abandoned. Most of the "laws" in physics or chemistry or in the sciences more generally are now known to be false. Theories can and are often more fundamental than laws. In general, we do not bother to classify findings in the sciences in terms of laws, theories, etc., or even bother with such nomenclature. Quantum mechanics is a theory but is rarely referred to as such (and is distinguished from the slightly archaic term "quantum theory" because this can be and often is taken to include both non-relativistic and relativistic quantum field theories), embodied cognition is a theory although I can't remember it being referred to as such, most models are theories, and most theories are not precisely defined in any one way nor are they encapsulated by any one interpretation or understanding.
There are issues in evolutionary theory that have not been resolved, despite the virtually incomparable evidence for evolutionary theory and the basically unanimous acceptance among scientists of evolutionary theory. The theory itself has grown as our understanding of the processes it seeks to describe has grown. Darwin, after all, knew nothing of genetics, and the double helix structure of DNA was only discovered in the mid-twentieth century.

This is nonsense. Most "laws" WERE shown to be wrong and are still wrong, others continue to be reformulated and redefined in order to be defined to be correct (e.g., the violations of the law of energy conservation in relativistic physics were reformulated in terms of the energy-momentum 4-vector or tensor conservation). I can't think of a single law that is "accepted as being universal" in any single form. Also, there is no strict divide between theory and hypothesis. That's why this nomenclature is almost entirely found in pedagogical literature or popular science literature (or nonsense crap), not the technical literature. String theory is called "theory" but not only hasn't been tested ever, it cannot even in principle be tested because there is no clear formulation of what it actually is (the basic mathematics of this mathematical unification framework have not yet been resolved, so there are no basic equations which one could use even to propose a thought experiment). The most fundamental law in all of science (the conservation of energy or whatever quantity energy is made to be taken together with) does not hold in general because, like most "laws", it is held to be true only of isolated ("closed") systems. Most of fundamental physics rests not on "laws" or "theories" but on postulates.

sorry to get here late....

proving evolution is a trick

I believe the notion is correct
and the intelligent guess (theory) explains so much about what we see in this world

but to set in place and experiment outside the petri dish
and to be sure there are controls sufficient?

evolution is an experiment
the earth is the petri dish
Someone Else is in control of the 'lab'
Someone ?.

This is too skeptical a take (which is your tendency). No scientific theory is universally applicable as of now, hence the laws within them each have their domain of applicability. Both Einstein's field equations of GR and the Schrodinger's equation or Feyman's QED equations are laws with their domain of applicability. Scientists don't call them laws because one is somehow supposed to describe the law in words in a succinct manner, and science has long outstripped such simple translatability.

You're not getting real answers to your thread question. You seem to already have what you think is the correct ''answer'', so I'm not going to waste any more effort on your confirmation bias.
Rightooo...
No, you aren't. You're getting /some answers that seem good to you, and your agreeing with those.
rotflmao

So other than demonstrating your bold empty claim, what reason did you post in the thread?

The whole " I know the answer but I ain't telling" tactic is so grade school and childish I am actually surprised to see you using it.

Threads like this highlight why so much confusion about Evolutionary science still persists in so many circles... It's unfortunate that we, on the internet, have so many hundreds of thousands of teaching tools readily available at our fingertips, yet we still lack basic and fundamental knowledge of topics that we wish to discuss.

It's odd.

If you have a strong opinion about a subject that you obviously know very little about, what good is your opinion?

Actually, his was the first site I came across that fairly well covered the three. Although lacking a bit, I think the descriptions suffice. :)

ok.....he calls hypothesis a reasonable guess
theory has some experiment
and law is proven

it's a reasonable guess.....til proven

some experiment would be helpful but would need be definitive to jump from the word....guess
then comes the word....law

The theory of gravity is still a theory
even though we could drop cannonballs from a height ....forever...
and the results are the same....forever

we still don't know how it works....and gravity is a theory
a good guess with experiment
but we are still guessing

because the substance cannot move without a push

the universe has been set in motion

by the snap of God's fingers
hence the rotation we see
So this man in the the sky just snaps his fingers and everything appears like magic, I see, that makes a lot of sense doesn't it lol.

no....it began in a void
a Spirit able to say...I AM....brought the universe into existence

the rotation would need be in play BEFORE the expansion begins
hence the catch phrase.....snap of His fingers
