First of all, even if creationism wasn't supported by science, it would still NOT (like evolution) be a religion.
If evolution is a religion, so is the theory of gravity or germ theory.
Secondly, evolution is a theory that people apply science to just like creationism is a theory that people apply science to. You are right that neither is a religion.
This is proof that you don't understand what a scientific theory is.
Creationism is an observation of reality.
Creationism is not supported by evidence. It is assumed to be true because the Bible is assumed to be true.
Science actually requires study.
You have this idea that people sit down, look at fossils, and ponder "hmm, I wonder what makes sense. Let's just plug in whatever sounds right and call it science!" That's not how science works. That's not how the theory of evolution works.
And Percepi's perspective here that evolution is equitable to atheism is false.
I never said that.
So the apologetical attack on atheistic morality, while a completely valid argument, needs to be restricted to atheism and not bleed over to evolution unless an atheist asserts evolutionary theory as a reason to reject Creator God's normative morality. Then the atheist's false assertion can, of course, be rebutted.
