A UFO doesn't mean an alien spacecraft :rolleyes:
After reading J.J.'s post googled "International UFO Bureau" and this was the first result.

For the record I don't believe UFO's are aliens. I believe they could be time travelers.
About time travel and UFO's I'm a complete "atheist": Aliens have never visited Earth; time travel is nonsense; life even at the level of slime and bacteria is nonexistent on other planets, etc.
Take the universe for what it is--a cold (4 K), empty (the number of electrons is far smaller than 100^100), dark (we can see billion year old blips of light just by looking at a night sky) physics laboratory.
