Not necessarily.
An idea that explains something could be called a theory. Good scientific theories are falsifiable which means you could prove it to be false. You can never prove a theory to be true, you can only provide evidence that supports the theory.
Scientific method means that there are steps to be taken while experimenting. In the beginning there is a hypothesis (good guess) and then all the steps in proving or disproving the hypotheses. The steps are important because other scientists have to be able to use the same methods and procedures to come up with the same answer.
Tribal communities are good examples of evolutionary theory of government, because the family unit is often important but overseen by a leader. A biblical example is the 12 tribes of Jacob because the head of the family formed the larger government. Each tribe was headed by one of Jacobs son, and Jacob ruled over them all.
The Best Defense is a good offense.
facing the diference of everything!!like house, language, social relationships, learning what means live good and ''ok'' in a diferent land. Lots of challenges for inmigrants start a new life in this country is a challenge too. Just to think about it is challenge but god bless america. Mexican woman..
No. It means that it was the best theory supported at the time it was formulated. Theories can change if new scientific evidence provides new information.

For proving the theory.
Not necessarily... it simply means the earlier theory was based on information available at that time it was proposed. Humans are pretty good at making advances in the scientific world... experiments almost always bring new information to light - allowing us to adapt or update existing information.
If all the evidence taken into consideration can be explained by the scientific model proposed and the model successfully predicts outcomes of experiments yet to be performed, it is a "good scientific theory" It still can be incorrect. If it is proven incorrect it should be abandoned.

a theorem rather, it has to be proven to become an accepted theory.

No. It simply means that someone thinks that there may be a different explanation. It is quite possible that the person challenging the scientific theory is wrong.Moreover, although Einstein disproved some of Newton's theories, we continue to use them because they are accurate enough for normal circumstances and are simpler to apply.
Evolution is a fact. The theory of evolution by natural selection is what you are trying to talk about. When someone says " evolution is just a theory " they are using the vulgar, common sense of the word theory. They mean guess, hunch and the like. The theory of evolution by natural selection is in the scientific sense of the word theory, which means a body of explanatory work supported by myriad lines of converging evidence that has been tested rigouusly and replicated often. Any good dictionary uses this scientific meaning of theory as the primary meaning of the word.
People tend to say that scientific theories are "just" a theory because of a confusion between the common usage of "theory" and the scientific definition. (In everyday speech people often use the word "theory" in the sense of a "hunch" or "vague idea". This is not what the word means in a scientific context). A scientific theory is deduced from observations and is the simplest way of describing natural phenomena. It is testable, observable, predictable, and falsifiable. Scientific theories are not the same thing as hypotheses, which are explanations that haven't been demonstrated or verified. A scientific theory has evidence to back it up. The common usage of 'theory' suggests an explanation that someone hasn't proven, or isn't able to prove. It doesn't imply evidence that has been tested; it doesn't imply predictability. When someone hears, for example, "Big Bang theory" or "the theory of evolution", they may hear the word 'theory' and associate those scientific theories with someone's opinion or suggestion. In reality, these theories are the best scientific explanations for a myriad of phenomena across multiple scientific definitions. In science, "just a theory" is a very good place to be.
A scientific 'theory" is science shorthand for "this is how we think it works". Sometimes the theory is developed without enough information (all the variables are e not known) and later observations and information shows the theory needs to be reworked. With enough information the theory becomes a very good model of what is happening and the changes become fewer and further apart.
