There seem to be a lot of people who misunderstand what the word theory means. Here is Neil deGrasse Tyson, scientist and friend to everyone except Pluto, on theories:
If you have a new idea and you want to test it, that’s a hypothesis.
If there is countless phenomena or objects out there, that have conduct or behavior, that can be brought under one umbrella of understanding. And that umbrella allows you to make predictions that are then shown to be true, then you have a theory… in an earlier day we didn’t call them theories we called them laws, but it’s the same thing.
In other words, when you say, “I have a theory.” You do not have a theory; you have a hypothesis. Theories have already been demonstrated to be accurate.
I have never heard of anyone comfortable with jumping out a window while claiming, “General Relativity is only a theory!” Yet somehow, this does not stop a ridiculous amount of people in the United States from not believing in evolution “because it is only a theory” without denying the existence of biology.
If you want to continue to deny the Theory of Evolution, go for it. I am not trying to convince you of anything other than it being silly to use words improperly. And since you now know what a theory is, please be aware that you are saying, “I don’t believe in evolution because it has only been proven multiple times.”
At least my hypothesis is that that sounds silly.
