Is evolution invalid or untrue because it is a Theory?
No, because the theory has been proven to be true via actual evidence.
This is like asking whether relativity is untrue because it is a theory. Well, it may be a theory, but the predictions that the theory make are indeed true. In other words, time really does dilate at high relative speeds and in gravitational fields. That's been measured and observed to be true.
So Relativity is more than just a theory, it's an observationally confirmed fact of life.
The same is true of Evolution. Originally it was just a theory, but the predictions of the theory have since been observationally proven to be true. So now it is no longer "Just a theory" but instead it's a proven fact of reality.
Those who claim that it isn't are just in denial of the overwhelming physical evidence that proves evolution has indeed occurred on planet earth.
In fact, the only people who argue with this are obviously religious zealots who prefer to think that a Santa Clause God created man from dust and a woman from the rib of a man.
And where is there EVIDENCE for that theory?
They have absolutely no evidence for it at all. None whatsoever!
So they have nothing but empty religious fanaticism that they cannot back up with evidence.
