I think I saw a UFO?

i don't think you're nuts nor do i think you're a liar (that answer should be removed as it's insulting) BUT anyway CONGRATULATIONS for (a) seeing a UFO and (b) for knowing that it doesn't necessarily mean a spaceship. See if you can find images (video ones) of a shooting star before you dismiss the possibility, then research all other possibilities and have fun doing it. Thousands of people would love to experience what you did on Tuesday night :-)
