From time to time the question is asked ....but once you explain light speed, just how far away other stars are & the like.
Most people are a little more sceptical of alians visiting earth !
Funny how reports of Alien visits are not usually made by Amateur astronomers
the people who spend more time looking at the night sky (where aliens come from !) that just about the rest of the population combined
The question of wheather we are alone in the Universe is a different matter & can not be so easily dismissed.
