Many people have a very distorted world view because they steep themselves in (at least) two cognitive traps:
(1) wishful thinking: an invisible man in the sky cares about me;
(2) motivated reasoning: doubting what I don't like, and clinging to my invisible man, regardless of cognitive dissonance.
It's healthier (in my view) to adapt to the universe as it is, rather than as I would like it to be.
"Every human is a thing of great significance in a restricted but important sense. On a cosmic scale, our physical presence is of no consequence. We are temporary assemblies of ten billion billion billion atoms, and in a century or less they will all be returned for recycling. But for the briefest of moments, these atoms are able to contemplate themselves. They will spend an eternity in darkness when we are gone. Our purpose should be to extend their moment in the light as best we can." Brian Cox, How to Build a Universe
Birth is a natural and amazing milestone following the coming together of DNA from a mom and a dad; it is the start of a life that will be created by the person who lives it: the ultimate creative act.
There is only one god. It is our self. We are the god of our lives; we create our lives by the choices we make as we go along.
"The metaphorical language of mythology is not denotative of actual worlds or gods, but rather connotative levels and entities within the person touched by them. Metaphors only seem to describe the outer world of time and place. Their real universe is the spiritual realm of the inner life. The Kingdom of God is within you." Joseph Campbell, Thou Art That
Death is a natural and amazing conclusion in that creative act. Each human life is but a momentary spark in the universe's long journey from the first expansion of space-time toward a steady increase of entropy, until, ultimately, the universe has become dark, cold and silent. Through death, we join the stars that burn out, the black holes that evaporate, the earth when it is engulfed by the red giant sun, and the human species that has gone extinct,
And honey, if you only get to be a momentary spark in the calendar of the universe, you may as well be as fabulous as you can be!
