No, I am simply saying what I honestly believe. An extraterrestrial
origin for UFOs is simply not possible. There are a great many
abbreviations around and not everyone is familiar with them. AI, SSME
(Space Shuttle Main Engine), SSTO (Single Stage to Orbit) We probably
use them far too much.

Given the age of the universe and what is knows about planetary evolution,
how old can the oldest intelligent civilization in the universe be? There
could easily be one a million years more advanced than earth civilization.
What about a billion years more advanced? Given the rapid progress of earth
technology I don't think it is possible to make any assumptions about what
an alien civilization would be capable of.
