No speed is any conclusive evidence of a UFO.
Yes it is .
Extraordinary speeds , fast or slow , to the extreme , is evidence of a UFO.
Extraordinary evidence is of course a body part, an instrument, faeces not of this world. Seeing something move at any speed may well be illusory or just plain vivid imagination.
Not really .
Extreme speed and the ability for an enormous object to hover , is just plain , reality.
In fact no conclusive evidence of life off this earth exists as yet, as much as I would like it to, and that is the official stance.
Off course the extent and content of the universe and the stuff of life being everywhere, indicates that life should arise elsewhere, but again contact between species is separated by time and distance.
Official stance ? Interesting , refer to authority ? When the authority dedacts information , from official documents.
The contact between species is seperated by time and distance ? Define both .
