Did I mention Creationism ?hahaha Darwin only came up with the theory, that doesn`t make it infallible. In fact, Darwin was wrong about quite a few things. Genetics was the big kicker that cleared up a lot of Darwin`s errors. Evolution can be seen and documented. Creationism can`t.
And it isn`t survival of the fittest, it is mostly survival of the most adaptable.
But you are correct about the good thing about science, it evolves as new evidence shows up. Creationism is just a primitive claim and not a very lucid one at that.
