Atheism is impossible

I'm getting ready to read the debate between Russell Glasser and Pastor Stephen, but in the first few paragraphs by Pastor Stephen, I was struck by the statement "...I believe atheism is untenable, irrational, and ultimately impossible."

This is worth a quick comment before getting back to my reading:

The idea that "atheism is ... impossible" stands out like the sun on a clear day. Atheism - the lack of belief in a personal deity, is by all measures, MORE likely to be a correct belief than theism, because a universe that does not include the complications of a parallel supernatural system to provide a basis for supernatural beings such as God, is inherently simpler and more likely per Occam's razor.

This ought to be interesting hearing the arguments on how it isn't!
