Here’s a digression, riffing off of what dad put into his last post.
For me, when I’m thinking about questions like “How did we get here?”, the ones that dad was pondering about in that last blog update, my brain shoots all the way back to the beginning. Not necessarily to the Big Bang, which I’ve heard described enough times that I’m not super interested in it anymore, but more in the history of Earth and the history of life on this planet.
(Here’s a good Big Bang primer, in case you’re not bored with it yet.)
Because the history of the planet and of life both fascinate me, partly because they seem simultaneously to be totally inevitable and completely improbable.
