Part 2: SOM1 -01 “Extraterrestrial Entities and Technology, Recovery and Disposal” TOP SECRET/MAJIC EYES ONLY

“Examination of remains recovered from wreckage of UFOBs indicates that Extraterrestrial Biological Entities may be classified into two distinct categories as follows:  a. EBE Type I. and EBE Type II.

... It is not definitely known where either type of creature originated, but it seems certain that they did not evolve on earth. It is further evident, although not certain, that they may have originated on two different planets.”
