Either way, you have a life and you're living it.

There is no evidence that we exist, either. The entire world may be an illusion as far as I know. The only thing I can really know for sure is that "I" exist in some form, as otherwise I couldn't have wondered about my existence in the first place. Descartes was right on that point, although I don't agree with his conclusions (such as God being the only explanation for my existence). However, I do think we have to live under the assumption that the world exists, otherwise society will collapse into nihilism.
But we cannot approach philosophical matters with the methodology of the natural sciences.
