After three decades of interviewing hundreds of people who have been contacted by extraterrestrial beings, Linda Moulton Howe has a compiled a taxonomy of the many types of non-human entities which have visited our planet. From grey-skinned humanoids to upright reptilians, she has uncovered a wide diversity of life capable of traversing vast cosmic expanses. She introduces us to her taxonomy of extraterrestrial beings on Earth and explores various motivations which have prompted their arrival. Some are new to the planet, while others have interacted with humanity for over 70,000 years and maintain close contact with Earth’s governments. This presentation by Linda Moulton Howe was originally webcast on March 15, 2017.
