Kiba and Ashlyn listened to Pythia's statements about humanity's fascination with immortality and everlasting youth.
"Immortality would mean eternal life, being exempt from death, and unending existence," Kiba said with a sigh. "As such, Immortality is against the natural order of the universe and thus impossible."
Pythia was obviously right about the lust the humans held for a long lifespan. After all, from ages unknown, humans have deep-seated fears and comprehension of their own mortality.
The era of evolution began in 1900, but even before that, the humans in the ancient kingdoms and empires invested heavily to discover ways to extend lifespan.
Not only the political and science class but even religions greatly focused on immortality. Epic books and sacred texts of almost all religion promised immortality and salvation to those who show goodness and follow the teachings of the god.
