One of the best dance sequences in all of Hollywood musical history.
Humans observe animal behavior and come up with hypotheses that become theories that become facts (or not). Some behaviors can only be described as a series of actions for their intents and goals cannot be discerned. What would other self-aware, intelligent lifeforms out there say about human dance? Would they go for the mating-ritual explanation or would they come up with self-expression (provided they had some form of dancing too)?
Of all the pondering and believing I do about ideas or truths, intelligent alien species is not something I fully accept or reject. I’m undecided.
