If one were to believe in something significant, then it should be in the immortality of Humanity, relying on its ability to live eternally and humanely across the expanses of the Universe.
What determines the readiness of modern humanity to undertake significant endeavors for the sake of a distant future? Mass extinctions have occurred on Earth, and humans are no exception. Yes, humanity is progressing, but not as it should. Perhaps, the primary resource is fruitful spirituality!
The key value of spirituality is its focus on making life more humane, creation of a reliable future for everyone, and Human's ascension to a more sophisticated state.
