The largest problem with everything you will present is that it is an argument from ignorance (Logical fallacy), nobody knows these things, and none of this is any conclusive evidence for anything other than ignorance. You say that theists call the beginning maker/creator god, but you fail to address the FACT that they have the same amount of evidence to support this as the naturalist, NONE.
The idea that something un-natural had to create the entire universe is again an appeal to ignorance, nature outside of the universe is not known at present, and therefore cannot be said to lack the mechanism for the universes existence.
Always existing universe in no way lacks common sense as opposed to created universe, you are stating an extremely weak opinion in that it is common sense to assume a beginning, not a logical or well defined argument. How does one coming to the conclusion God(s) always existed takes more of a stand to the side of common sense, this is bias, plain and simple it is not common sense.
As far as the scientific evidence I think if you ever go back and change the video, you should clarify the expansion of the universe, as from everything I have read, the galaxies do not accelerate, but rather the space between cosmological bodies expands, this is important and should be noted.
