We know nothing, but I find illusions comforting. The modern scientific theory of a importent part of the universe, with the most physical proof is quantem physics. And it says the universe dosn't exist when we don't look at it. Isay the if reality is an illusion, then illusions are reallity. I don't care if I live in a world of mist and abstracts, the importen thing is to LIVE. Life is a great adventure, So live it. Help those around you, make a splash, and live life well. and the afterlife? Well, to quote peter pan "Death will be a great adventure"
