Among all the species on earth, humans have an unique gift of contemplating over the higher purpose of life. Humans can be philosophical. Inscriptions on Paul Gauguin's famous painting "Where do we come from? What are we? Where are we going?" has a profound relationship to our existence. Philosophers since ages have tried to answer these questions. Every religion tries to explain the purpose of life in its own way.
Unfortunately, there is no convincing answer to why we exist, perhaps because it is beyond the world that we perceive through our senses. We could try to find a convincing answer all of our life and still might not find one. The fundamental question of why we exist is a singularity. This singularity is neither mathematical nor theoretical. This singularity is existential.
