The importance of being on this earth bears a much a deeper meaning, an attainable importance of keeping humanity as the symbol of eternal legacy.
This would symbolise a mark of human success and achievement beyond time and space, then to spend countless amount of wasted effort focusing on philosophy about
the origin of humans
why are on we this earth?
what is the meaning of life?
Human legacy is one way of addressing the issue, it is an underchallenged idea and must be addressed as the answer to those both questions.
