My brand of agnosticism says "I do not know these things and I've seen no evidence yet to make me think otherwise."
I'm open to the possibility I could be wrong - and I think many agnostics are as well.
ID is agnostic about the mechanisms that drive evolution: the neo-Darwinists are not. The extreme Darwinists approach to mystery is always: well, our methodology inevitably will eliminate that mystery. Why not admit the obvious. Just as Aristotle’s methodology proved inadequate because it explained TOO much, so might even our scientific methodology because it is not comprehensive enough. If we small beings can grasp the whole of the universe, we are claiming not just god-like powers but the very powers we might deny to THE GOD. Given that a wandering asteroid could wipe us out amost in an instance, whence comes this arrogance?
