Naomi, at the risk of this evolving into another long, pointless conversation, let me respond to your last post: You state "Where's your evidence that intelligent life does not exist elsewhere in the universe? ". My answer is, I have no evidence. I am not making the claim that there is no other life. There may well be, I hope there is! Infact, I am not making any claims at all, I am not suggesting for one moment that I know all the answers, I am just looking at the available evidence, I am not arrogant as you suggest, I simply don't know. I am open-minded. I do, however, not BELIEVE that crop circles are created by aliens. This is the fundamental point I was making. I need some kind of evidence, not belief. Belief, (to me at least) is not a viable principle, in that it ignores evidence and observation. As I have previously stated, there is, to my satisfaction, plenty of evidence to show that human beings are responsible for intricate crop circles. Therefore I don't seriously need to investigate the idea that aliens are trying to communicate with us via the medium of cereal. That just not make sense to me. Lets just say we are never going to see eye-to-eye on this matter, you beieve in aliens, and although I would truly love to know they were visiting us, I need some evidence. Let's just move on, shall we?
