That video is nothing more than a continuation of our previous use for God "I don't know what happened at this point, so God must have caused it."
Over history, we've used God as a placeholder due to human's need to attach a reason for everything.
"God created the sun and the Earth"- actually those were formed from debris left over from a super nova explosion.
"God creates the weather" - actually those are results of air currents caused be heating from the sun.
Etc etc...anything we couldn't explain, we would use God as a placeholder until an actual explanation was discovered.
The beginning of the universe and the medium out universe resides in is no different. The problem with getting actual scientific data from these points in time and these areas is we rely on some type of radiation to see happenings that far back. The fact that the universe was "dark" during that era makes it nearly impossible to see any happenings. We currently use computer simulations to reverse the data we can see to calculate what happened during the dark age, and so far it is consistent with the Big Bang theory.
We've also seen evidence that our universe isn't the only universe, and "bubbles" of universes are floating around in an inter-universal medium a lot like bubbles in soft drinks. These bubbles may form spontaneously, or form when one bubble collides with another. Each of these bubbles will most likely have their own laws of physics, as the balance of physical forces appears to be randomly distributed---which means we happened to have struck the lottery and live in a universe that allows matter to coalesce in such a way that life can eventually form. If gravity, for instance, was a bit stronger or a bit weaker, we wouldn't be here to wonder about it. Molecules simply wouldn't be able to form the way they do now. (On another note, gravity in our universe SHOULD be a lot stronger than the effects we feel now, but most of it is "leaking" somewhere. That's another lecture though ).
So, in a nutshell, simply equating "I don't know how that happened" with "evidence of God" is not evidence, it's assumption. Historically, every time we've said "God did that", it's been proven to be a part of a bigger system that didn't require a supreme being.
As for myself, I have an open mind about God. There COULD be a supreme being, but this being's role would be a lot bigger than any of use could imagine, and a lot different than anything in the bible. We would be so insignificant in the scheme of things that this "god" would not be paying attention to us as we would be mere specs on a spec on a spec on a spec. If you're looking for a god, you can look to the physics of our universe. Physical laws are what created us, so simply saying "God is physics" would be an accurate (but limiting) title.
