Why are we on this earth?

This question is about justifying our presence on this earth which means to know what we are exptected to achieve through this human life.

Are we here just to add kilograms to this earth? Are we here just to arrive in this world one day and depart from the world another day? Are we here just to eat, sleep, reproduce like lower species which do not possess power of intellect like us ?
Sientific accomplishments are not higher achievements because they do not offer any solution to the problem of never ending desires.

What is the aim of the human life? When we delve into the question of aim of the human life, manyfold answers emerge. But careful analysis shows the only one motive of seeking satisfaction is all important. Everything is sought for making an individual happy and satisfied.

But again the question what kind of happiness we are looking for needs a proper thought. It is clear that anything that makes us happy, brings us happiness which is ephemeral and shortlived. The urge to be happy is never permanently satisfied. Unless this urge to be happy is satisfied forever no one can have any respite. It means that we are in search of the permanent happiness.

In other words, The of aim of human life is 'We want to live forever and be happy forever.'

Thus we human beings are on this earth to seek the permanent solution to the problem of never ending desires through attaining eternal and infinite bliss.
