An alien, as in extra-terrestrial, has never been seen
Alien X
Apparently, there have been strange sightings, but there has been no evidence or proof that an extraterrestrial being (alien) has actually been seen.
There is no proof that aliens exist. I believe there is no such thing as aliens. Has anyone seen an alien ship? Has anyone seen an alien? No.
no
No, but there was an 'Alien' skull seen hanging on a trophy wall in the ship at the end of Predator 2.
Scientists have not seen an alien, so there is no proof of which color they are.
Nobody has ever seen an alien if they even exsisted.
on the video game the last alien seen is Alien X but at the end Azmuth gives ben Master control and ben slams down the omnitrix and in a flash of green the cut scene is over. on the hour-long TV movie "Vengeance of Vilgax" ben gets Diamondhead back
