I have always liked the comparison (adapted from Mark Twain) that a partial solar eclipse is to a total solar eclipse as lightning bug is to lightning.

The moon has really just arrived at the “sweet spot.” It’s been departing from us ever since its creation four billion years ago ... the moon is only now at the correct distance from our planet to make total solar eclipses possible. In just another few hundred million years, total solar eclipses will be over forever.

The fact that such an aesthetic marvel exists only fleetingly — on a cosmic timescale at least — precisely during the period of time when we will be here to appreciate it, is only "bizarre" or "coincidental" for those who lack eyes to see...
