ALIENS have contacted us because we are not advanced enough yet, according to a bizarre theory.
As far as man goes, we are still very young in comparison to the Earth, let alone the universe.
Some experts believe, as a result, we are nowhere near ready to be contacted by aliens.
The Fermi Paradox states that as the universe is potentially infinite, it should essentially be teeming with life, so why have we not found any evidence yet?
One theory to explain this is that a civilisation essentially becomes so big that it becomes impossible to sustain itself and dies out.
Another is that there simply is no other life out there.
Or, it could be that we are insignificant, with some believing that we are currently in the ‘zoo’ stage, where advanced beings are currently observing us until we are ready to be contacted.
With the universe being 13.8 billion years old, man’s oldest ancestors have only been around for about 0.36 per cent of this time, and modern humans considerably less.
This implies that a civilisation is likely a head start of at least millions of years on us, meaning that we still probably seem like chimps in comparison.
But, due to the technological advances made in the last century alone, a mathematician has calculated humans are likely to be contacted by aliens within two millennia.
Cornell student Evan Solomonides said: “We haven’t heard from aliens yet, as space is a big place – but that doesn’t mean no one is out there.
“It’s possible to hear any time at all, but it becomes likely we will have heard around 1,500 years from now.
“Until then, it is possible that we appear to be alone – even if we are not.
“But if we stop listening or looking, we may miss the signals. So we should keep looking.”
