I am often amazed at how much of my body works without me having to do any work. Food is digested, blood moves around, my hair grows, my cells fight off infection, if i cut myself... boom... my body fixes it.
In fact, I have very little control over much of anything. I suppose I can decide which color socks to wear or which flavor ice cream to eat... but even with those choices, its quite mysterious to me HOW I decide which I like.
The reality is that most things happen without any conscious intent or diacernable reason. The big bang, the stars forming from dust and hydrogen, the creation of complex atoms, the formation of planets and the evolutionary process eventually leading to intelligence that can finally reflect on and begin to understand the process that lead to its own creation.
It's a lot of amazing things.
