Note that Dr. Hawking says "it may be possible." and "would start" and this was back in 2005
Then in Sep 3 2010 in the following article he states this: "The universe began with the Big Bang, which simply followed the inevitable law of physics," Hawking writes. Because there is a law such as gravity, the universe can and will create itself from nothing. Page not found - The Daily Galaxy
Some modern theoretical physicist believe the universe can and will create itself from nothing. This is due to the nature of the laws of physics.
We already concluded there is no explanation for where these fundamental laws have come from.
So your premise that the universe can not be explained is flawed. It can be explained by using the laws of physics.
what can not be explained is where these laws came from. There may or may not be a answer. Maybe the answer resides in another universe, Or maybe the laws are self existent.
Your right if you mean to say that no one can explain where the laws of physics came from. But the universe's existence is a direct result of the Big Bang. That has pretty much become the most accepted theory to date.
