The reasons not to believe in extra-terrestrial life are steadily dwindling.
That is the view of US astronomer Professor Eric Wilcots, who is one of the speakers at SciFest Africa 2008, the annual event which began in Grahamstown on Wednesday last week.
Wilcots chairs the astronomy department at the University of Wisconsin, a key member of the international team behind the Southern African Large Telescope (Salt) in Sutherland, in the Northern Cape Karoo.
