Are there evidences of evolution that justify calling it a fact? Here's a simple explanation of why evolution is both a fact and a theory.
By calling this site "Proof of Evolution," I'm saying that the fact that life on this planet evolved is provable. There are varying shades of theory as to how it evolved, but anyone with a big enough shovel can see that it did evolve.
That's pretty much a smoking gun.
The question is, what happened?
Tiktaalik Rosae; intermediate between fish and land animals, found because the consistency of the evidences of evolution—both in layers of the earth and geography—let scientists know exactly where to look for such a fossil.

Did God kill off all the old life over and over again, and then create similar but different life forms, leaving only a small percentage relatively unchanged? Or is it possible that something could happen so that over time, that old, very different life, could evolve into what's around now.
The question is, is that really possible?
We now know it's possible. Every living cell on the planet reads the same DNA. We even produce insulin for diabetics by taking a human gene and putting it in yeast, so that the yeast will produce insulin for us!
We know that DNA changes, and there are some genes, especially those that are in multiple species, for which we can trace the changes.
Those sort of evidences of evolution seem irrefutable to me.
Asked about what evolution evidence is the most irrefutable, Richard Dawkins answered in the following way. Dawkins is a renowned atheist, but fact remains fact, even if we Christians don't like it. Jesus Christ is, after all, in our opinion—certainly in my opinion—the Truth, not what we wish were the truth. Jesus isn't afraid of the facts, even if you are.
It's a bit difficult to end a page with a word from Richard Dawkins, so let me give you this link to a debate that he held with John Lennox in which I was very impressed with Mr. Lennox.
