It shouldn't be, since in science the word "theory" means more than a musing or a thought. For a hypothesis to reach the theory stage, it must have been tested against data and consistently and reliably proved to be accurate. The only bias is towards empirical naturalism; an axiomatic property of scientific enquiry.
there might not be enough proof
A "law" contains absolute certainty or scientific truth. A theory is very close to being a law, but without the absoluteness. That is what a theory is. If you have a pretty good idea of how something in science might work you might form a hypothesis (hye-POTH-uh-suss). With enough additional proofs and evidence, a hypothesis may someday turn into a theory.

Some one proves it wrong.
Yes. A hypothesis or theory allows you to predict what you might observe scientifically. Sometimes your theory is wrong. It must be tested. Some of mine have been way off.
Theories are ideas, educatied ideas, but still only ideas. A scientist may change a scientific theory if new facts or information are found, if other scientists' review find errors, if attempts to apply the theory are unsuccessful, or if they see that the calculations are wrong when they double check them, and so then they would retest and rewrite their theory to correct the errors.Science is testing a belief with the means to disprove it and being unable to do so.Scientific Fact = something that has yet to be disproved.
Yes, evolution is a theory. But it is not "just a theory" in the sense that you probably mean. In layman's terms, we might speak of a theory as simply an idea or an opinion, such as "Well, that's YOUR theory..." In science, it is something else entirely, and when something becomes scientific theory, it has been very well substantiated. It is more synonymous with the word "fact" in this usage, unlike the previous usage I used as an example. in fact, all scientific discoveries are considered theories. hell, the fact that our bodies are made up of cells that reproduce is still just a theory.
a model is different than a theory a model is an actually picture or structure of something a theory is what people might think about something
A hypothesis is an eduacted guess, and a guess has no previous knowledge about it.A hypothesis is usually part of a scientific experiment which involves a method for testing the hypothesis, and either supporting it, or supporting the opposite, the null hypothesis.
Because technology might change in the future.
Continuing research can turn up new or conflicting information regarding a theory or scientific law. It will then be changed even after general acceptance.
