The sun crested the eastern sky sometime around six this morning. Its early luster shined onto water, grass, rock, flowers, and trees. Men and women waking to its rays, or to various alarm clocks, all experience the same waking sensations.
Do we need to know that the reason the sun does what it does because we, as residents of this space-rock, rotate around an axis that causes half the globe to face light and the other half to face a dark, spatial vastness?
No, probably not. But we like to know. We have a thirst for exploring the unknown. That’s part of what makes life so exciting.
