This explanation seems to ignore the likelihood that God spoke life into existence.
As in speaking some sort of language.
(Fascinating, how the genetic code is a form of language.)
The "something" that got us from nothing to a massive universe is the Word of God.
The Word of God gave us the Big Bang. The laws of physics that unfolded from that Big Bang could have led to an early "warm" period in the universe that was essential in the development of precursors to life that were eventually deposited on Earth.
