After reading this, nothing seems impossible for life on other planets and even in our own solar system. Just to think about Enceladus, Titan and Europa, makes me wonder...life way under the ice crust is really possible...

And what about Mars ? if in fact water or ice is under it's surface, why isn't life possible !

It certainly is thought-provoking. If you think about it, NASA photographs show what seem to be building ruins on Mars, you can't discount the possibility of an ancient civilization once existing on the planet...
