Well except for one thing. Even if the Big Bang were an explosion (it wasn't an explosion in the sense of a bomb, a common error from the people that denies it) it didn't make any noise at all.
Noise needs air to propagate. If a rocket explodes in its way to the Moon, a person in a few meters from it will not hear anything, because there is no air out of the atmosphere. So there is no sense in applying the "Word of God" to the Big Bang because it was not a word at all .Maybe you can apply it to "God's Light" because there was a lot of light from the begining, given that light travels in vacuum. But once again, you can apply ambiguous words to almost anything you want.
