Surely the 'vs' is for: Evolution v's Intelligent Design, the differences ad law cases are well documented.
Maybe the thread should have been called Evolution OR Intelligent Design?
Evolution and intelligent design can coexist. How is it vs?
They are two rival theories, for one, that offer completely opposed ideas as to how life started (and evolved). Intelligent Design is, I believe, discounted among evolutionary theorists, as it cannot be tested or proved, and is therefore outside of scientific/evolutionary theory.
From the point of view of ID, it is possible to suppose that a designer created the original beasts, and they 'evolved', however this implies that a 'intelligent' creator was unable to create perfect beasts, and that they needed to evolve... etc...
So, I guess they can co-exist from a ID point of view (as the evidece for evolution is there, but from an evolutionary/scientific point of view, ID is a non-starter.)
