Quote:An alien race will fly trillions of miles just to play hide and seek with earthmen? I don't know if you are describing an advanced alien race or the cast of Jackass.
I just think they're unmanned science/survey probes. There won't be anyone inside of them. Given the turns they can make at the speeds they travel anything organic inside would probably be mushed anyway. There was one that followed the Apollo mission to the moon as well, it's an event recorded on the audio logs there was definitely something there.
