Why Does the Universe Exist At All?

Have you ever stopped to consider why the universe exists at all? It seems that left in the vacuum of infinity with nothing to start with, nothing would ever have been created?

To me the greatest mystery and the greatest gift is that we exist at all with these precious gifts of life, love, consciousness and unlimited possibilities to become anything, do anything and have anything our heart's desire...

It is my current opinion that nothingness can be defined as infinite possibilities (or more Scientifically as a superposition of ALL possible Universes existing simultaneously as pure potential). So there is no need to think that everything was created from nothing, because nothing has always contained everything...
