HUMANITY is woefully unprepared in case of an alien invasion, the man who is leading the search for extra-terrestrials has claimed. Seth Shostak, senior astronomer at the Search for Extra-terrestrial Intelligence (SETI) which is leading the charge in the search for alien life, says that there is no plan if aliens decide to visit Earth. Mr Shostak blasted the US government for not taking an interest in SETI's objective and compared the world's current response protocol to aliens as if neanderthals were to meet the US Air Force. Speaking to Live Science, Mr Shostak said: "As far as I know, there's nothing, and I think I would have heard something because of the [SETI] false alarms. "Some people asked me at a conference last week, 'What plan does the military have to deal with aliens should they land?' And I said, 'I don't know … but to the best of my knowledge, they don't have a plan.' "It would be like the Neanderthals having a plan in case the US Air Force showed up." Mr Shostak also
