(31,261 posts)You should know that refraction, absorption and/or filtering out of some wavelengths of light totally changes the perception of what is seen.
Some people that claimed to have seen UFOs simply saw some phenomena that a scientist with the right training seeing would explain as a function of light being altered to give an illusion of an object when there was none. There are potentially many life containing planets, as I have pointed out over and over, some with beings that are much more intelligent than even our brightest. To say that we have not been visited is no more correct than saying that we have, neither of us possess intelligence that are centuries past our capabilities and both of us can only project forward what we know, believe or theorize on.
