If extraterrestrial existence is known by the world governments and/or NASA, it may be due to the mass panic and hysteria that would result in directly disclosing it. We're an incredibly stupid and violent species, if they're hiding anything it's probably for the best. Although knowing the US government, they'd probably be doing some sort of illegal exchange with an extraterrestrial civilization and trying to cover it up.
It was built went into space a bunch and got retired. That is all. But there is a conspiracy that the Nasa Space shuttle was built by aliens. Aliens landed on earth in the shuttle and nasa took it repainted it and put on their logo. To this day there is no proof that this has actually happened. The aliens were not with the ship which leads them to believe the aliens are still our here among us.
We will never get a straight or truthful answer from any branch of the US government.
yes. we think other species are aliens because we dont know what they are. maybe aliens dont know about us and think we are aliens.
becuuase they want to know more about the human race rember we are aliens to them as well are they to us
Aliens do not come to our planet but they are real.
We Don't Know Yet.
What you mean is, 'When will the aliens return'? ...or why are aliens upon us. you must mean when will the aliens take over, well what I know is that they wont take over the world or galexy while were alive.
This, we may never know.
We do not know because so few aliens have had the decency to talk at length to us about their situation at home.
they could be curious like us, they could just want to know if they are alone, like us. My opinion is they don't mean harm.
they could of been and the government didnt want us to panic
They aren't. There is no evidence for the existence of aliens and certainly no ground bases. Because they don't want people to know what they do with the aliens and where they are because then we would go try and see the aliens and ruin their experiments with the aliens.
