People don't judge a fish negatively just because it can't climb a mountain (maybe some do).
It doesn't makes sense to judge something negatively just because it doesn't meet the standard of the judger.
The fish's purpose is to swim, not to climb mountains.
Likewise, it doesn't makes sense to judge a human as an irrelevant being just because it lives in a water ball whirling around a hot ball throughout the big empty space for some billions of years until everything explodes.
Man's greatness is not measured by how long he lives or by how big he is physically.
Man's greatness is determined by how close he is to his creator (god).
