The risks that may occur in case of presence of superior alien technology could extinguish the whole mankind on earth.
A scientist and astronomer from the SETI Institute has cautioned that if aliens visit Earth, they will be the ones to “set the rules”.
If aliens manage to travel across space to Earth, it could be very bad news for humans.
This alien technology if required would be far in advance of our own and could be used to enslave us.
“If they showed up on our doorstep, that means they have this alien technology that is considerably far more advanced with respect to ours,” she said.”
“And because of that, they’re going to be the ones that set the rules.”
The SETI Institute also believes that part of the reason we’ve yet to contact aliens is that our technology might not necessarily be compatible with theirs.
The institute is constantly sending radio waves out into the universe in the hope of receiving a response. But there’s nothing that says aliens will be aware of or even use radio waves to communicate.

“We may not have invented the right way to do this yet,” concedes Tarter, who obtained a PhD in Astronomy from the University of California, Berkeley and worked as a Project Scientist for NASA’s SETI program before it was terminated in 1993.
She has received two public service medals from the space agency.
The second reason we may not have found ET yet is due to the sheer vastness of space.
According to Tarter, if you look at space as the equivalent of Earth’s oceans, then on the same scale we’ve examined the equivalent of a glass of water.
“If there is a civilization out there that is only 1,000 years older than we are, who knows what type of technology, or what type of process, they’ve put into communicating with others,” agrees Dr Nathalie Cabrol, who now heads up the SETI Institute.
Interestingly, while SETI might think we’re some way off communicating with aliens, NASA reckons we’ll do it in the next couple of decades.
NASA astronomer Kevin Hand said: “I think in the next 20 years we will find out we are not alone in the universe.”
NASA Administrator Charlie Bolden added: “I would venture to say that most of my colleagues here say it is improbable that in the limitless vastness of the universe we humans stand alone.”
Mars and a number of moons in our solar system have been the focus of the search for alien technology and life for decades.
But new telescopes launched into space have massively increased the number of planets outside our solar system that may support life.
