I recall that as a child I had vague notions about the planets in our solar system.
Why is ours one way and the others not?
Ours has life because it is this certain way—it was the toss of the dice that determined that one would have life and the others not.
Their size, their positions, their orbits, their constitutions—it was all arbitrary.
Life was an accident and I just happened to be there to think about it.
The universe’s origin was arbitrary.
Its makeup was arbitrary.
Our galaxy’s shape was arbitrary.
Our solar system’s position in the galaxy was arbitrary.
