Compelling Evidence for the Big Bang?

I am surprised that Hemant Mehta is so impressed with this exam answer a student gave to a question about the Big Bang:

On the one hand, theism doesn’t posit a floating man in the sky. And in context the suggestion is self evidently silly, since by definition, there was no sky before the Big Bang. And no gases. The answer botches both science and theology, badly.

But on the other hand, if one anthropomorphizes God as a “floating man in the sky,” then how would a powerful being of this sort snapping his fingers and creating a universe look different from the Big Bang?

I think the student’s answer was disappointing from the perspective of not only theology and science, but even in terms of the impression it gives of atheists. Am I missing something?
