Where do we come from? Is there a purpose to life? Where did the universe come from? Below is a short write up on how a rationalist can approach these “life’s persistent questions” – about origins, meaning and destiny. This is not meant to change any one’s mind – as I am least interested in “evangelizing” what I think is true as I believe every person is intelligent enough to have their own ideas about life, cosmos, evolution etc. But I request you all to read the point of view of a rationalist. Unlike the explanation of a religious person, who can explain anything in 10 seconds by saying “that is what my holy book says”, a rationalist argument takes time to explain, but way more interesting and intellectually satisfying.
