do you realize how much you sound like Jehovah's Witnesses?

Harsh, but not entirely unfair. There is certainly a strong vibe of "you must see the world our way or you (and the children you are misleading) are all doomed." And it is not entirely correct to say that bible followers think there is no higher revelation. As St Paul puts it: "For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known".

It is because of such things that I suggested we examine the question of what we really mean by a species, as that should not be a world-against-pete discussion. It is hard to justify an "Origin of Species" unless one is clear what constitutes a species. And, as I hinted, I suspect we are less certain of this than we imagine. Over the years I grow less convinced that a 'visiting alien' who wanted to organise all creatures into groups would end up with even a similar set of categories to those we have.
