Non-existence (nothingness) is impossible since everything arrived through an existing physics. The existing physics is something (not nothing); and since some always existing physics was able to produce our Universe, its likely that it has produced infinite universes through infinite time.
With only one universe the odds of having a seemingly designed universe with conditions suitable for life are extremely small. This apparent design of our Universe can easily be explained by the Multiverse (more than one universe) theory. The Multiverse brings up the possibility of there being a huge (or infinite) number of universes, and also the possibility of there being a huge number (or infinite number) of universes with life. Astronomer Martin Reese covers this in his book Just Six Numbers. If any number were minutely changed, our Universe would have been completely different.
For example: if the amount of matter in our Universe would have been a tiny fraction different, our Universe would have quickly collapsed or quickly flown apart and no life could have arisen. Some have proposed a many universes theory to explain this (each universe with its own conditions). This greatly increases the odds of there being a universe suitable for life.
