If Bigfoot or the Loch Ness Monster really existed dont you think they would have found a dead one by now? So I say no way. But I do absolutly believe there is other life out there, knowing what I know about astronomy and random genetical selection. Question is, is there intelligent life? There could be dinosaurs out there galaxies away. And if you believe in ghosts and the ability for the spirit to continue, then you would have to conclude that God also exists. And I believe he abssolutly does.
