- "For a long time, the Earth has been watched and studied—
- the advent of humanity has been watched and studied,
- humanity’s technological process and progress have been watched and studied,
- awaiting the time when the Intervention would be attempted." 
"Humanity has lived in isolation throughout its entire evolution with only very brief encounters with races from beyond the world." 
"This world has been the focus for many races for a very long time because of its biological diversity and its strategic position in this well-inhabited part of the universe. The Earth has been observed for a very long time. It is of great interest to different groups for different purposes." 
Ancient Attempts vs. Now
"Those who are intervening in your world today do not represent races who have visited long ago, and thus have no right or claim to this planet or to any inherent association with the human family." (The Allies of Humanity. 
Past Use of Earth as Biological Storehouse
"Worlds such as yours are quite rare and are therefore highly prized and regarded by those in the Greater Community who are aware of them. Indeed, your world has been used as a biological storehouse and resource for millennia by several different races."
"Some have come here to gain biological samples from the immensely rich diversity of life in the world. Others have come here to hide things, to store things beyond the awareness of the native peoples of the world." 
Interplanetary Communications of Old
"Certain native groups were given wisdom about life existing beyond the world. This was demonstrated to them by visitations and by the giving of gifts. This existed in tribal nations long before and, in some cases, after the existence of early human civilizations."
"Attempts have been made to establish colonies on Earth, but these colonies have all failed because of the biological hazard. The native races of your world were far too primitive to be considered important relations—important enough to establish major interbreeding activities. Attempts have been made to influence earlier cultures in your world, but the results have not been significant."
"Many thousands of years ago, in your time, several races came to interbreed with humanity to give humanity a greater intelligence and adaptability. This led to the rather sudden emergence of what we understand is called 'Modern Man.' This has given you dominance and power in your world. This occurred long ago."
