I find this legend about other earths remarkable for its time and quite extraordinary. It is of course suggestive of contact or at least knowledge of alien worlds and life forms. -- Book-Lover.com
When Adam was cast out of Paradise, he first reached the lowest of the seven earths, the Erez, which is dark, without a ray of light, and utterly void. Adam was terrified, particularly by the flames of the ever-turning sword, which is on this earth. After he had done penance, God led him to the second earth, the Adamah, where there is light reflected from its own sky and from its phantom-like stars and constellations. Here dwell the phantom-like beings that issued from the union of Adam with the spirits." They are always sad; the emotion of joy is not known to them. They leave their own earth and repair to the one inhabited by men, where they are changed into evil spirits. Then they return to their abode for good, repent of their wicked deeds, and till the ground, which, however, bears neither wheat nor any other of the seven species. In this Adamah, Cain, Abel, and Seth were born. After the murder of Abel, Cain was sent back to the Erez, where he was frightened into repentance by its darkness and by the flames of the ever-turning sword. Accepting his penitence, God permitted him to ascend to the third earth, the Arka, which receives some light from the sun. The Arka was surrendered to the Cainites forever, as their perpetual domain. They till the ground, and plant trees, but they have neither wheat nor any other of the seven species.
Some of the Cainites are giants, some of them are dwarfs. They have two heads, wherefore they can never arrive at a decision; they are always at loggerheads with themselves. It may happen that they are pious now, only to be inclined to do evil the next moment.
In the Ge, the fourth earth, live the generation of the Tower of Babel and their descendants. God banished them thither because the fourth earth is not far from Gehenna, and therefore close to the flaming fire. The inhabitants of the Ge are skilful in all arts, and accomplished in all departments of science and knowledge, and their abode overflows with wealth. When an inhabitant of our earth visits them, they give him the most precious thing in their possession, but then they lead him to the Neshiah, the fifth earth, where he becomes oblivious of his origin and his home. The Neshiah is inhabited by dwarfs without noses; they breathe through two holes instead. They have no memory; once a thing has happened, they forget it completely, whence their earth is called Neshiah, "forgetting." The fourth and fifth earths are like the Arka; they have trees, but neither wheat nor any other of the seven species.
The sixth earth, the Ziah, is inhabited by handsome men, who are the owners of abundant wealth, and live in palatial residences, but they lack water, as the name of their territory, Ziah, "drought," indicates. Hence vegetation is sparse with them, and their tree culture meets with indifferent success. They hasten to any waterspring that is discovered, and sometimes they succeed in slipping through it up to our earth, where they satisfy their sharp appetite for the food eaten by the inhabitants of our earth. For the rest, they are men of steadfast faith, more than any other class of mankind.
Adam remained in the Adamah until after the birth of Seth. Then, passing the third earth, the Arka, the abiding place of the Cainites, and the next three earths as well, the Ge, the Neshiah, and the Ziah, God transported him to the Tebel, the seventh earth, the earth inhabited by men.
