[We're unaware of it because it simply doesn't happen.]
Oh really? Then why haven't scientists explored the possibility that the earth was created out of water? The answer is simple; because it's in the bible. So the goal of most scientists is to disprove the bible. but if they included all the evidence in their findings, they would see that the over 54,000,000,000,000 gallons of water vapor in the universe, the fact that the human body consists of over 80% water, that the oceans and water all over the earth comprises more of the earth than land, and the fact that all animals gestate in water, is a much more plausible explanation then one Big bang, then they might open their eyes to the origins of the universe instead of making up their own changing stories that are nothing more than fantasies.
