Nobody is arguing evolution within species, there is nothing to 'believe' there. The problem comes when people try to use evolution to somehow prove that the Bible is incorrect by insinuating the man 'evolved' from some other creature, or that all living things evolved from one beginning 'spark' of life. That has not been proven. Evolution as it is today does not disprove anything about intelligent design.
Totally agree.
However not be able to disprove something doesn't make it a viable topic in a science class.
That's fine, as long as the science class doesn't say that evolution explains the origins of human life or implies that human life evolved from a completely different species therefore negating the concept of an intelligent designer.
I'm not going in that circle again, as long as you're conceding that creationism shouldn't be in science classes, that's good enough for me at this point.
