It's fun to pretend, but there is no proof and so there is no good reason to believe this. The universe is really big but that does not prove that aliens exist. After all, someone in the universe has to be the first, and there is no solid proof it isn't us.
Aliens are real because we can't be the only life in the hole of the universe and some people think there are labs holding aliens.
no
There is no proof that life exists anywhere but Earth.
It broadcasts radio signals to the sky, so that aliens can figure out that an intelligence exists on Earth, and find us.
aliens dont exist
Since we don't know about any aliens, there is really no way to know.
they say people long ago talked with aliens
Maybe, humans might be from Earth.
It is not known if aliens exist and if the do, we know nothing about their biology. If life beyond Earth exists, some organisms are probably slimy while others probably are not.
probably not in the earth, but VERY most likely far away. we will probably die off before we come into contact with aliens.
There is no scientific evidence to confirm that Earth has been visited by aliens. Many reported sightings and encounters can be attributed to natural phenomena, human-made objects, or misinterpretations. The search for extraterrestrial life continues, but as of now, no conclusive proof of alien visits to Earth exists.
We won't know until we can all see them.
The way the question was originally spelled, I can't tell if it was trying to ask if aliens really exist or asking where they are. Assuming that we mean "space aliens" here, the answers to both are the same: We don't know. There's no credible evidence that life exists anywhere but Earth (a couple of inbred mouth-breathers claiming to have been "probed" is not "credible evidence").
