SETI chief says US has no evidence for alien technology. 'And we never have'

If all the reports of mysterious objects buzzing our skies are taken as true encounters, the Earth appears to be under assault. 

But spoiler alert: For the chief leader of the SETI Institute, established to search for and understand life beyond Earth, there's a need to step back and cuddle up to a cup of cosmic reality. 

"We don't have any evidence of any credible source that would indicate the presence of alien technology in our skies. And we never have," said Bill Diamond, president and chief executive officer of the SETI Institute, headquartered in Mountain View, California. "The idea that the government is keeping something like this secret is just totally absurd. There's no motivation to do so."
