When you stand in front of a mirror and look at your reflection in a mirror placed behind you, you are reflected into eternity.  You can't count the reflections because they are endless.  The mirror image in front of you or behind you is finite but the reflections are infinite.

Our universe is considered finite but it could be nothing but an atom of a larger universe, which is an atom of another universe, etc., etc., ad infinitum.  For humans to try to understand the full scope of this is fruitless.  To try to explain it or assign a creator to it is absurd.  Thinking in finite terms, we say "Well, someone created matter".  But matter could be as infinite as the creator we assign to it...it can't be created or destroyed, only transformed.

There is a thread that holds this all together.  I prefer to add the extra "o" in God and call it Good.  If more people believed in Good rather than God our little boson of a world would be a better place.
