These ages and events are cited by Rudolph Steiner and Plato:
pre-12,000 -11,000 BC - The time of "The Golden Age"
The Sphynx was set up at the end of this period
"The deluge" occurred
The ancient Vedic peoples existed - divinely inspired and 'connected' with the higher worlds
... and then "something" happened.
From then on, humanity started losing consciousness.
The feeling of "separation" and "fear" starts appearing.
7,000 BC - The time of "The Silver Age"
The "mental age"
"Consciousness" was reduced to around 75%
The pyramids were built
"Religion" ruled rather than 'connection'
