   Sarah's post with those strange animals makes me wonder if the possibility of other life (beyond the terrestrial realm) out there be totally impossible. If large animals right in our backyard can go undetected for so long (think of the okapi from eastern africa or ceolacanth) what makes the possibilities of living organisms (such as plants, bacterias, and stuff) be totally in the realm of impossible somewhere in the universe? I admit that the idea of sentient beings whom have the capabilities to reach us via the ways of the UFO is a bit hard for me to swallow (this given that life is carbon-based) but life itself I think would find a way to be if given the chance.
