BBC World Service - The Forum, Aliens

Why do some people believe in aliens and extra-terrestrials, and not others?

What lies behind stories of alien abduction and invasion? And can aliens or outsiders sometimes be a force for good?  With Nnedi Okorafor, Chris Thomas and Richard McNally.

What do you think about the possibility of extra- terrestrial life? Are we alone in the universe? And what do aliens reveal about us? Bridget Kendall asks ecologist Chris Thomas, science fiction writer Nnedi Okorafor, and psychologist Richard McNally to pool thoughts about what aliens mean to us.
