Observation
We see these creatures in different shapes & forms that are so closely tied to humans yet so far. Our homosapien narcissism compels us to relate. In a way giving us humans a pedestal to observe and be the judge of what's going on in this world.
At a distance they can seem very different but at the core, their values, morals and history is closely tied to what we humans have experienced. The more we assimilate to these creatures, the more we realize we are more similar than different.
