      This is the reason why, sticking to the facts and failing for the time being any exhaustive, satisfactory explanation other than their “biological nature”, we agree to your interpretation, according to which most of the UFOs that have mystified men for generations are not extraterrestrial spaceships at all, but are generally-invisible, ultradimensional, ultraterrestrial, biological, etheric organisms that are of our planet, that have been living with us, side by side, unnoticed, since the beginning of time.
