20001-nen Chikyuu no Tabi

In the year 20001, three aliens arrive on the ruins of Earth to investigate the extinct human race. Revering humanity as a highly intelligent civilization, they wildly misinterpret the artifacts left behind: mistaking playgrounds for sacred places, umbrellas for communication devices, and graveyards for farmland. The team consists of a warm-hearted yet misguided captain, a highly logical but often inaccurate analyst, and their innocent, instinctive young member. While the two adults obsessively analyze human civilization through logic and theory, the youngest slowly begins to understand humanity through emotion, contradiction, and empathy, discovering that what science cannot decode, the heart just might.
