Question: What should be the meaning or purpose of life to an athiest?
Answer: The purpose of life is the same for an atheist and a religious person.
Neither atheism, nor religion – as we consider religion today – can help us in reaching our Human purpose in life, as both atheistic science and religious belief remains within the domain of the inherently self-serving, self-justifying, subjective Human nature.
In order to reach and fulfill our Human purpose we need to become similar to nature’s single operating, life-giving force, purposefully and methodically “clothing into” the “godly qualities” of selfless, altruistic, unconditional love and service of others.
Neither common science, nor blind belief, or any current spiritual practices can help us in this regard, as all searches within our present, artificial and false world built by and governed by the ego.
We need a true, objective, Natural (non-Human) scientific method, which can harness, employ Nature’s evolutionary force, in order to finish our Human development, providing us with an “operating software” upgrade, neutralizing, redirecting our 100% egoistic, introverted consciousness, perception of reality with those “godly intentions”.
Then atheists, nihilists, religious or spiritual people will all become alike, uniting in our common Human purpose.
