We are currently searching for life on other planets by trying to first identify planets in the Goldilocks Zone
, a region of space in a given solar system not so close to central star as to be too hot, but not so far from it as to be too cold.
Assume for a moment that there is advanced intelligent life out there, and such beings have visited Earth in the past and found primitive man. After working out a pidgin in which to communicate, early man asks the visitors something along the lines of why are you here?
or how did you find us?
