The first UFO sighting may have taken place in 329 BCE, when Alexander the great described two great silver shields that swooped to attack his armies, startling his soldiers, horses and elephants to such an extent, that the battle had to be postponed to the next day.
"Ridley Scott's Alien was released in 1979."
The first alien visitor genre movie was released in 1902 and it was called, "A Trip to the Moon."
As for the first recorded Zhor'i encounter. Who knows. Read a bible.
If you mean creatures from other planets, there is really no firm evidence that they actually exist.
There have been meteors seen by people for as long as they have been around, so it would not be known who was the first person to see one.
Galilao mapped the moon and saw jupiters moona

Yes, you could use a telescope to find a UFO.
It would be impossible to say. There have been reports of UFOs in the skies over Earth for thousands of years.

That would be before written history. We can't know who the first person was that saw something flying and couldn't tell what it was.
If a UFO was found by a person, then it was no longer flying and no longer unidentified; therefore, no longer a UFO.

So few sightings are actually reported, there is no way to know that answer.
Officially, it would be October 2011. Unofficially, Jan. 2012.
"UFO" does not mean alien spaceship. So far there is no scientific reason to think even one alien spaceship has ever landed on Earth. UFO just means "I saw something in the sky and I personally don't know what it was."
Not that I know of.They went to the moon to experiment, and also to be the first country (USA) on the moon. :D
In his basement, high....
