This is something that I find particularly intriguing about the place we
live on:
Not the fact that the earth does have a moon. Nor the fact that it is
the only one the earth does have. Not even the remarkable fact that it's
an incredibly huge chunk of rock for such a small planet.
No, what's most astonishing about this all is that its apparent size
matches so well with that of the sun.
I can only think of two possible conclusions for this:
(a) It may be due to the anthropic principle, i.e. there might be some
hidden mechanism in the creation of intelligent life that requires this
extraordinary property.
(b) It was /designed/ to be this way.
