In science, a theory is a major idea that is supported by numerous observations and/or experiments and that explains a broad range of phenomena. In everyday language, the word theory is used as a synonym for a hypothesis, a guess, a hope, a bias, or even a wild idea

I must say that evolution falls under everyday language.

Sorry, I can't agree with that. The theory of evolution has been supported by new data and tests for 150 years, and is stronger than ever.

So, what was observed? And I won't take "dead stuff" as an answer.
