Question
Have there been sightings of UFO's while you are in space? Also i would like to know if you have ever seen an alien?
The answer to both questions is No. As discussed here previously (check for UFO entries by using the search engine), no astronauts have seen UFOs. Certainly I have never seen an alien, nor have I come across any convincing evidence that anyone else has either. The modern myth of aliens visiting Earth is not supported by the evidence.
