how many moons does earth have?

One night I went out for a nice walk. The full moon lit up the one way street that I live on. As I was walking I saw one other person walking by. It turned out to be Buzz Aldrin. He was one of the first people on the moon. (the second actually) That is unless your one of those nuts who thinks the moon landing was faked and that there are secret moons that the government has hidden in Area 51.
