What causes the molecular motion, Amos? Energy? Science is an attempt to describe reality with words (definitions), but words will always fall short of fully describing any reality. Reality can be experienced, but no series of words will ever serve to completely explain what is experienced. Words are mere conventions, agreed upon within a closed loop by those who already know those words. To someone else outside that particular loop, it doesn't matter. But...heat is perceivable, and will always be perceivable, regardless of what words you use to describe it. The same goes for Love and for Light. Without a knowledge of molecular vibration, you still have heat and you still experience it.

Dewey, you are so right. Politics is the Great Divider. It sets people against each other who would otherwise be the best of friends. It has caused the unneeded deaths of billions.
