Starpeople came and went from the Earth continually; they used different ways and means of travelling to and from here. Digital cameras have captured some images of starships. The tall white Arcturians were here, with their white hair and blue eyes. They created knowledge and opportunities to work with and for Mother Earth. Other starpeople were here, they broke the Universal laws with the creatures they made (who still exist in other dimensions), and allowed their self interest toward power and force prevail. These caused wars, and the Fall of Atlantis.
Many of the cities and townships in the time of Atlantis were created by the starpeoples themselves; they were created along lines of sacred geometry – and the sacred geometry contributed towards the functioning of the cities themselves. The starpeople were of different races, and so had different diets; some were nourished by heavy foods, some were nourished by lighter foods, and some simply lived on the love and light of the Source of All. The starpeoples had natural ceremonies giving thanks to the Source of All, and the light beings from Sirius, after genetic engineering had taken place, taught the up-standing apes to practice burial ceremonies.
There are many who refer to a race as “Arcturian”; in fact there are different races that have come here from the star Arcturus. Edgar Cayce did describe one of these races accurately. In pre-Atlantean times, there were conflicts, and there were wars on the Earth. The Leonines (from Sirius) who were helped by yet another race from the constellation called Sirius, engaged in a brief war with the Reptilian races.
Yalarm explains that there were many races on the Earth; some came and visited, some came on the mission of the Mothership Rexegena (those on the Rexegena were from many galaxies and universes) and some were already on Earth, the reptilians, reptoids, annunaki, etc. Many built civilisations, even civilisations based on love and the human values. Due the Fall of Atlantis, much was lost, and scientists still bump up against the “missing link”. Artefacts and scientific instruments are found that could not have been created by cave-dwellers. 
Yalarm tells of the history of Earth and how the Humans were genetically engineered. Before the Fall of Atlantis, there were many races of starpeople coming and going on Earth. Electricity was generated and distributed through grids under the Earth. The grids surrounding the Earth closed up somewhat to prevent the catastrophic energy from going out and affecting other planetary systems and galaxies. This is now loosened to admit the energy from the Source of All; it will raise all life forms on Earth and bring the Golden Age.
