It's all very puzzling indeed. The fact carbon was created through the nuclear fusion of three helium nuclei at the centre of stars seems unlikely, due to their unstable nature. They also need to collide at the exact same moment, which also appears quite improbable. But there is a "resonance" which helps the nucleosynthesis of carbon, causing stars to produce vast quantities of the stuff. Basically, it seems like we live in a "Goldilocks Universe" where the conditions are perfect to harbour life, but how life got to this point seems statistically impossible and extraordinary.

To follow up on what EG said about our relation to the cosmos as participants. Are we here as the universes' bitch in a way? Does the universe need an observer to exist outside of a superposition-like state? Maybe that's our purpose as conscious beings.

I also like the low-entropy multiverse theory, where we were always going to live in a place so finely tuned for life and that we can potentially "see" the fingerprints of alternate universes through string-like vibrations within atoms.

This is all quite a new subject for me, so I hope what I said makes sense.
