Please read my post, I presented evidence that can be confirmed if you take the time to visit the proper museums, fossil dig sites and archeological sites.

Theories are stated as Theories and not as Laws because it is impossible to prove anything 100% in the real world. That's why the only Theories to become Laws are the very simple ones... the Laws of Thermodynamics, etcetera.

But calling something a Theory does not state that it is necessarily untrue... just that we are 99% percent sure it's true, but there are exceptions to the Theory. These exceptions may be due to environmental causes such as catastrophes or diseases. Mass extinctions have occurred numerous times in our history... the oldest found killed off the trilobites, who were the fittest sea creatures ever, and should have been around till today. The most popular killed off the dinosaurs, who were very successful, from an evolutionary standpoint.

Evolution is a Theory because there are times when "survival of the fittest" doesn't work out... but 99% of the time, it works. The Thermodynamic Rules are Laws because you can't change them... ever. Energy never goes uphill... at least not in the visible universe.
