To the greatest extent possible, Dr.
Farrell's books draw on the body of knowledge
contained in such fields as astronomy,
cosmology, physics, anthropology, genetics,
etc... They tie most of the UFO issues together
in one coherent picture and provides an
explanation of the sciences contained in the
field of UFOlogy. His books consider the logic
that supports the existence of extraterrestrial
intelligent (ET) life and the evidence for ET
intervention in human development as recorded by
the Sumerians; evidence for ET contact through
crop designs; and explanations of how UFOs do
the amazing things they have been seen to do and
much more.
