Many scientists subscribe to the notion that "Nature is all there is" which is a philosophical statement but not a scientific statement. Science has a hard time making absolute statements, especially when singular events are beyond observed duplication. A little more humility from the "scientific community" would be appreciated on this score, but theirwidespread paranoia demands an absolutist mentality .

Question for theistic evolutionists: "Can God acheive an intended result by a process devoid of intentionality?"
Very true, but this is the crux of the matter in teaching evo vs ID. The evos will say that what they are teaching is "science" devoid of "religion", and that ID is "religion" devoid of any "science". The problem is that both have a philosophical presupposition that cannot be proven with the scientific method.
What needs to be pointed out is that any origin theory is based in a philosophical presupposition, and as such, has a certain amount of faith to it.
