In both the distance measuring of space, and the agriculture issue, there is much left to speculation. None of this can be taken as pure facts. I think it's more of putting your faith in evolution in the end. I'm not speaking on biological terms as I know next to nothing about genetics, ect. But the common issues surrounding human life for over 194,000 years doesn't match up for me. So I guess i'll leave it at that... However, I do appreciate all the insight that was shared and have come out of this feeling smarter; Thanks!

P.S - That was an interesting link JCL, thanks for posting it. After looking in to the different scientific fields in space tonight, I must say, I'm rather suprised how specialized things are becoming. Theres even a field dedicated to researching stars and only stars. Neat.
