<i>"Actually David Stone created them."</i><br /><br />That one <i>almost</i> went over my head!<img src="/images/icons/smile.gif" /><br /><br />They do mention objects like these being found in caves, but its not clear if the same process is invovled in the natural formations. <br /><br />They even mention the tube-like formations in the martian meteor purported to contain fossil evidence of bacteria-like life, But those objects are much too small to imagine that they were created by a process involving bubbles. Other non-life processes have been suggested for those objects. In fact, one would have to say the non-life proponents have the upper hand in that argument, from what I've read.<br /><br />Anyway, the point I was trying to make was, even for compelling objects, ones that the most natural response to would be: 'well, of course that's a living -- or formerly living -- thing', it ain't necessarally so. It will take a <i>lot</i> more work to verify: life, or non-life.<br /><br />After all, they're still debating over that martian meteor (ALH84001). And that's here in our best laboratories, not far away on Mars with remote sensors as our only access. <div class="Discussion_UserSignature"> </div>
