Atheism is unreasonable

[pocaracas]

He did say "Universe", not "the entire cosmos".
And as far as we know, "the entire cosmos" may be the Universe. Whatever lies beyond it, if anything, is unknown. This is a known unknown.

Even, granting your terminology correction, how does that change anything?

It changes a lot. If Vilenkin is saying that the universe began to exist, and Guth is saying the universe may be eternal...and they both made the damn theory together, then they may mean "universe" in different contexts.

Perhaps the theory allows for both interpretations. As such, it is not the final word on the subject that you wish it to be. Have you considered that?

The entire cosmos, with its capacity to, somehow (quantum foam?), generate Universes, being of infinite space-time does what for the god hypothesis?

Infinity problem.

Say it like a little kid: There is no infinity problem.
