Aliens on Earth

If aliens visit Earth, they’ll take charge

It’s said the truth is out there, but we might not like what we find if we ever uncover it.
A leading scientist involved in the Search for Extraterrestrial Intelligence (Seti) has said that if aliens visit our planet, they could take control thanks to their use of superior technologies. This would give them an edge and ultimately lead to them ‘making the rules’.
Astronomer and co-founder of the Seti Institute Jill Tarter told TechCrunch: ‘If they showed up on our doorstep that means they have technologies that are considerably advanced with respect to ours.
‘And because of that, they’re going to be the ones that set the rules.’ However, she explained that a species can perhaps only develop sophisticated technologies, such as the ability to travel long distances across space, if it has learned to behave in a peaceful way. This suggests ET may be relatively friendly and co-operative – good news for humans if Earth is invaded. Seti is looking for radio waves and optical signals in the universe that could be signs of alien technology, but Dr Tarter admitted: ‘We may not have invented the right way to do this yet.’ Dr Nathalie Cabrol, who is leading the hunt for alien life at the Seti Institute in California told MailOnline an advanced alien civilisation may be trying contact Earth, but we can’t detect the signals. While astronaut John Grunsfeld said last year that if aliens are out there, they already know we exist. He said an advanced alien civilisation may spot humans from afar by tracking the changes we’ve made to Earth’s environment.
‘We put atmospheric signatures that guarantee someone with a large telescope 20 light years away could detect us,’ said Grunsfeld at the Astrobiology Science Conference in Chicago.
‘If there is life out there, intelligent life, they’ll know we’re here.’ Dr Cabrol believes that in our lifetime we will find simple alien organisms close to Earth and a replica of our planet in another galaxy. Nasa’s chief scientist Ellen Stofan agrees, he recently said we could find evidence of extraterrestrial life in 20 to 30 years.
‘We know where to look, we know how to look, and in most cases we have the technology.’ Jeffery Newmark, interim director of heliophysics at the agency, added: ‘It’s definitely not an if, it’s a when.’ ‘We are not talking about little green men,’ Stofan said. ‘We are talking about little microbes.’
