The advent of a Lanonandek Son on an average world means that human will, the ability to choose the path of eternal survival, has developed in the mind of primitive humanity. But on Urantia the Planetary Prince arrived almost half a million years after the appearance of human will. About 500,000 years ago Caligastia, the Planetary Prince arrived on Urantia. There were about one-half billion primitive human beings on earth at the time of his arrival. He established his headquarters in Mesopotamia. ( This is the same place the Anunnaki settled and the same time they touched down, yet there is no mention of them in the Urantia book. There are several theories as to the origins of Homo sapien sapien, but one thing they did not do is evolve from primitive hominids such as Homo erectus or Cro-magnon. I like Sitchin’s idea that the Anunnaki wed their own genes to the genes of Homo-erectus to create a slave race for the mines and other hard work. It wasn’t until much later that the “gods” uplifted humanity and taught us how to build the civilization of Sumer. But all of that is suppressed in the Urantia book.
Caligastia had a reputation of loyalty and devotion to the welfare to the universe of his origin, but he also had a certain restlessness coupled with a tendency to disagree with his superiors in minor matters. Melchizedek, the author of this paper 66 was on Jerusem when Caligastia went to Urantia, and he did not then realize that Caligastia was falling in love with himself; he did not understand the subtleties of personality pride.
The Planetary Prince brought with him all sorts of assistants and administrative helpers. His associate-assistant was Daligastia, also a secondary Lanonandek Son. There were a host of celestial and angelic persons assigned to promote the welfare of the human races. The most interesting of these were the Caligastia 100. These were not invisible to human like the other staff members were. They had actual physical bodies. I think this is because they would be interfacing with humans from the tribes and teaching them domestic skills. The main job at first was to turn the tribes from hunters to herders, with the hope that man would turn into a home-loving and peaceful farmer. The settlement was a beautiful city with walls 40 feet high and the temple to the unseen Father in the middle. Outside the wall all colors and classes of humans met for schooling. The teachers would teach the especially bright students and send them back to their tribes to teach those children.
The 100 were material but superhuman beings. It was the custom for these teachers or assistants to create new creatures before they retired. There were 50 males and 50 females and they didn’t know what sort of creature they would give life to. The 100 had souls because they had progressed through the morontia worlds and gained citizenship on Jerusem. During the mortal life in the flesh the soul is embryonic. It is born (resurrected) in the morontia life and grows through the successive morontia worlds. Anyway, the second and seventh of the 100 were exploring the various non-sexual ways of producing offspring and accidentally produced a primary midway creature. Soon the other 98 got into the act and they didn’t stop until they had produced 50,000 primary midwayers. These midwayers came with all the skills they needed to be helpful in any situation. And they could affect physical reality if necessary.
