No, it looks pretty clear that Jixxy is being told to NOT teach evolution as something that might be factual. As in, not both sides presented as equally plausible, but just one side presented. Creationism, full stop.
What I was instructed to cover was what evolution is. But I cannot in anyway endorse it as truth or even being possibly true. I can't say that creationism is in anyway not possible.
I do have a really hard time with this kind of thing... it's a theory that the world is flat, too, but we don't have to teach that the world might be round or might be flat, these are the two theories.
Although in this case it's really, "The world is flat. Oh and some people might think it's round, but whatever."
I wish I had some constructive advice, Jixxy, as I think you're doing a good thing in sum by volunteering in an organization that provides help to people who really need it. But what a tough spot.
