Reptilian types and those of the human types came from different fragments of consciousness in the sense of polarity, such as a line of a magnet or magnetic bar, the positive pole on one end and the negative pole on the other end; if this bar were made of light or consciousness, and one end of that bar were to develop faster than the other end, the faster growing end would become the head, the other end the tail.
* Now, if the positive end of the bar became the head, it would result in a creature different from the bar in which the negative end became the head whatever creature is created it has a positive and a negative side, and one side is energized more than the other. The positive side, if energized more, becomes the head, and the negative side, if energized more, becomes the head.
* The Reptoids were born out of the negative end of such polarized energy, and the mammals were born out of the positive side of such energies, and they are, of course, many degrees in between. Thus, you see the cat with its cats eyes having certain qualities similar to that of the Reptoids and Greys and the dog with its round eyes and round pupils having certain qualities and facial features more akin to that of the human.
* The difference between humanity and the Reptilian or Reptoid types is that humanity is accompanied by the evolutionary growth and development of compassion, while the Reptoids have stripped away compassion from their being and have become technologically cold, efficient, powerful.
