I believe the universe was created 14 billion years ago from a singularity and what we today know as the big bang theory. From that single moment in time, all of the Helium and Hydrogen in the universe was created, the basis for the existence of everything we know today. Every single atom ever was born in that moment and exists today, surrounding us, engulfing us. Four billion years ago the solar system was born out of an accretion disk creating the milky way we see today. The initial blast from the big bang (and assuming we all know a bit about inertia and vacuums) pushed everything in an outward motion, which continues to this day. Hypothetically (and this can never be proven), the universe will reach a limit of expansion at which it will slow and inevitably stop before it starts shrinking unto itself once again, eventually back into a singularity and possibly creating yet another big bang. The cycle of this means that perhaps on the grand scale of things, this has happened before. Other universes could have existed and others can exist again. Who knows?

I suppose this can be viewed as somewhat "spiritual," but it seems lacking to me. I do not praise, pray or cower. I do not judge. I question, I ponder. I refuse to preach but I will sit and converse. No one is right, to me, because nothing can ever be proven.

We are all stardust. Today, as much as when I was a child, this idea remains with me and comforts me.

This is my "religion," I suppose. My science. This is what I believe.

Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.
-Lawrence Krauss

This is so true. I completely agree. And I LOVED the quote.
