Prequel: Younger Dryas meteor impacts, the Flood & Atlantis

Evidence of an ancient human civilization that flowered between 18,000 and 12,000 years ago. Traces left by this culture point to technology that in some disciplines was not that far behind us. Evidence points to remarkable skills in medicine, precision stone working & finishing, large scale logistics and large scale project management. Achievements also seem to include manned flight and artificial light.
