The universe is a vastly desolate place and in total entropy rises. Locally, howevere, there ARE fluctuations around this average rate, so that instead of absolutely everywhere more and more chaos arising (although on average more and more chaos may arise), there are in places the opposite: structures arise. In particular the mechanism of gravity is metaphysically speaking a force against chaos: things organise themselves together.
Having these pieces of observations, in order for there to be a pocket of the universe, where order arises with such success as is exhibited around us, there universe has to be an incredibly vast place. And in fact our universe is extremely vast.
So the view is not completely without basis. It might not be completely right. But it is not obviously wrong.
Consider the rhetoric use to say, that there be life elsewhere in the universe: fast amounts of desolation don't make sense. This is not true: the emptiness and barrenness does fulfil a purpose, as shown above.
I agree with aleph nought: this is no doctrine of Materialism. Materialism simply makes claims about what substance all things must consist of, in order to exist. It denies the spiritual dimension as having any ontological reality. Within this world view there are serious views about how phaenomene like consciousness might be explained. (Even if one disagrees with them, they are really worthwhile listening to as they are very informative for pragmatic naturalism.)
The claim that materialists believe that tornadoes sweeping through junk piles enough times give rise to jumbo jets, is just pure nonsense and nothing short of a straw man fallacy. A materialist (would not propose but rather) takes on the explanation provided by the naturalist, that namely through a process consisting of a complex interaction of diversification, selection, and selforganisation, organised structure SLOWLY (but surely) arises. This is not PURE chance, but rather chance+selection/filtration given through the environment+self-organisation (necessity).
