Writing on Space.com, Leonard David says; “Probably not, but there are reasons to be optimistic about our near-future prospects.”
He goes to say that scientist have "found more than 4,000 exoplanets in three decades, as the numbers keep rolling in, observation says that every star in the universe can host more than one star."
He also asked a top SETI (search for extraterrestrial intelligence) experts for their advice in gaining site for intellectual life.
Seth Shostak said that apart ,from the typical ways to getting infornation, there’s also luck: "And, of course, there's always the unexpected," Shostak said. "In 1996, the biggest science story of the year was the claim that fossilized Martian microbes had been found in a meteorite. No one really saw that coming. So one can always hope to be taken by surprise."
The Martian microbes were bogus, and so it seems that the rest of SETAs tactics are also. One can only get life from an intelligent source.
