How did Adam and Eve populate the earth with only two sons?
Adam and Eve had many children, not just two male sons.
The events that transpired between Cain and Abel typifies the conflicts not only between individual humans but also typifies conflicts between human groups as well.
Even today we can identify which group of humans play the role of Cain and Abel. Today, oppressors play the role of Cain while the oppressed play the role of Abel.
One must be able to understand the difference between the literal and the metaphoric to get a grip on this topic.
The rise and fall of civilizations is a wave phenomenon or spiral and should be viewed as such.
Where literal interpretation ends metaphoric interpretation begins.
There have been many “Adams and Eves” who have come, bred and raised children and passed away. Life and civilization is a wave phenomenon or a spiral and not an upward arrow.
Who came before Adam? If one can fathom the wave phenomenon, the best answer to this question is “Adam”.
The biggest clue that this approach is correct comes from the incontrovertible fact that the earth’s climate follows what is known today as the Milankovitch cycles.
Following the Milankovitch cycles, whenever the earth becomes colder, life recedes: whenever the earth's climate undergoes an ice age, life recedes.
The second big clue is tradition.
Noah is the second Adam according to the Middle Eastern tradition. What happened was that a comet which crashed in the Caribbean caused a worldwide cataclysmic flood which destroyed much of human civilization. Atlantis was destroyed in this way. Today, we find the Azores which are truly remnants of Atlantis.
This cataclysm rebooted human civilization. The dust which lingered and blocked sunlight caused a cooling of the earth.
The so called flood myth does have basis in reality. Massive floods have occured and destroyed much of human civilization. Even aboriginal Australians have a so called flood myth.
From Adam to Noah is one civilizational cycle and from Noah to the current civilization comes after that. The cycle of the rise and fall of human civilization is a wave phenomenon.
Technology: In the previous civilizational cycle, stone technology was used extensively with stone pyramids strewn across the globe. Obviously, they understood the idea of the acoustic phenomenon as a source of power. Stone pyramids of the past formed coupled oscillators with the earth: the power of resonance to harness the energy from the earth.
Energy from the earth is a form of stellar power because of geometrical considerations. Earth and the stars are manifestations of the torus.
The Ancient Egyptians understood this and did not hesitate to use expressions such as extracting energy from the stars to mean extracting energy from the earth.
The chief architect of the Ancient Egyptian pyramids was Enoch who was an intellectual. Islamic tradition calls Enoch as Idris which means “learned”. The root consonants are DRS.
