Curiosity: How Did This Show Get Greenlighted?

So the Discovery Channel is kicking off a new series called Curiosity, in which a series of guest hosts come on and tackle the universe's most inscrutable questions, such as "Why is sex fun?" and "Could we survive an alien attack?"

As banal as that already sounds, the premiere show is "Did God create the universe?" and is inexplicably hosted by Stephen Hawking - the same Stephen Hawking who is already on the record as stating that no, God did not create the universe. Are we supposed to feel any actual suspense about the outcome of this question? This is like having a show called Curiosity: Is Obama a Socialist?, hosted by Michele Bachmann.

But the one that gets me is the alien attack episode, hosted by Michelle Rodriguez. Of course, her credentials in science are impeccable - she's been expelled from 5 schools, drives drunk and once banged Vin Diesel - but at the risk of stepping on her toes, I would say that no, we have no chance of surviving an attack by a race of aliens advanced enough to build ships that can traverse thousands of light years.
