(What percentage of stars have solar systems that contain or once contained intelligent life?)

"I believe a complex set of circumstances allowed for intelligent life to develop on our planet.If the dinosaurs had not been wiped out i doubt that man would have had s chance to even evolve let alone exist.Therefore the chances of intelligent life existing elsewhere is slim.Let's face it,we are trying our hardest to find and contact alien life why would'nt they be doing the same?If they are intelligent and advanced it is easy to know that if they had no curiosity they would not have become an advanced civilization."

(Do you believe that there is life on Mars?)

"I suppose my answer is based on the fairly simplistic premise that if I have no available evidence to incline me to believe there IS life on Mars, then the hard-wiring that manages my thinking forces me into the belief that there is no life on Mars. However, I do remain always at the ready to shift my belief regarding life on Mars (as I am with pretty much everything) by varying degrees, right up to and including 100% certainty -- to the point of becoming & being yet another incarnation of Eric Hoffer's "True Believer", with all the rights, privileges, and self-righteous indignation thereunto appertaining."
