Let me exchange a question for a question. How do you know for sure that there is any other life in the universe except you? You could be no more than a brain in a jar, or in one of the Matrix pods, and no one exists except in your own mind.

How would you prove it otherwise?

In the world of philosophy and science, we do not know whether life exists outside of ourselves or outside of our planet, or not.

We are desperately spending billions of taxpayer dollars sending probes to Mars and to orbit Jupiter and Mars, hoping that on some planet or moon we might show at least a microbe exists outside of Earth.

So far we haven’t.

If we could show life exists outside Earth, it might give us some amunition against scientist’s age-old enemy: the dreaded creationists.

It’s a stalemate at the moment.
