How are the amino acids found in lunar soil different enough to make us suspect they're the product of life? (On the other hand, maybe the amino acids found in space are the product of life?) http://news.discovery.com/space/have-you-heard-the-one-about-life-on-mars.html So even when we think we found signs of (past) life, it may turn out that there are non-life processes that produce the same signs. The only thing that will settle a question like that is coming across a living organism. And even then folks are bound to argue about where it came from. -- Helge Moulding mailto:[log in to unmask] Just another guy http://hmoulding.cjb.net/ with a weird name
