NASA astronaut Stan Love has exclusively discussed aliens with The U.S. Sun and explained why he thinks they haven’t visited us yet.
Love is a 57-year-old American scientist and astronaut who joined Nasa in 1998 and went on his first spaceflight on Space Shuttle Atlantis in 2008.

He’s logged over 300 hours in space but hasn’t seen any signs of intelligent life around Earth yet.
Despite Nasa now officially investigating unexplained UFO sightings, Love doesn’t believe intelligent aliens have come to take a look at humans just yet.
His first theory is that there could be intelligent aliens out in space that just don’t want to visit.
He told The U.S. Sun: “You could imagine intelligent life that just doesn’t care about technology and is just perfectly happy to stay home and doesn’t feel like they need to build starships.”
Love things there could be aliens out there that our intelligent in their own right but don’t want to or can’t visit.
“You could imagine intelligent life that we wouldn’t even recognize as intelligent like imagine coral reefs that are complicated enough to each be at their own intellect and they speak to each other through coded pulses of fish larvae and sea urchin eggs and we would have no idea.
“Dolphins on Earth are pretty smart, we can’t communicate with them, we can’t relate.
“So alien intelligences may be much more common than we think but we just don’t recognize them because they are alien, they are so different from us.”

The space expert also theorized that intelligent alien life elsewhere in the universe may have wiped itself out before it could find us.
Love told The U.S. Sun: “I see in reputable sources, they talk about a great filter, something that stops technical civilizations from developing to the point when they can master interstellar travel.
“What that might be is you poison yourself with your own waste, you cook yourself by altering the composition of your atmosphere because you think it will make you rich to do that or you blow each other up with really powerful weapons.”
His third theory is that there are aliens far more intelligent than us and that they don’t want to waste their time visiting.
Love said: “A civilization that can master that kind of energy probably has nothing to do with us. We would be interesting scientifically I imagine. It’s a subject of a lot of debate.”
Nasa and space agencies across the world continue to hunt for signs of alien life or even evidence of ancient alien life that has since died out.
Love thinks we might still find aliens in our life time if they do visit or send out radio signals that we can detect.
