The position of the Sun relative to the Earth affects, I find, my life rather significantly.

Yeah, but you're just a believer.

The position of the planets relative to Earth effects its eliptical orbit and therefore climate. The position of the stars is a useful guide for navigating.

I guess thats why they're astrologers and not astronomers.

What pedants we are.

The position of the Moon relative to the Earth affects the lives of those who ply the sea.

No, can't think of anything else.

Oh, I suppose it also affects the lives of those trying to find their way around in the night, in the savana.

But aren't we 'lighter' in the daytime?
