There is truth in this clip. Galactic Humans' lifespans are 1000+ years, as desired. DNA is repaired "up there" and functions optimally. When you don't live on a radioactive polluted Cabalist prison planet even the basic things can change dramatically for the better.
Yes, the Atlantis was a great civilization once, but they were responsible for the Great Flood themselves because they degenerated from spirituality into insanity. I never heard about the Grand Canyon's role in this.
Socrates was based, the Cabalist overlords of that time hated him. Not sure what's your point with the years though, lifespans degenerated after the Great Flood which happened 12000 years ago, we all have our DNA shafted since that time.
