Of course you have physical birth and death, but is there anything more to life than physical? Plus the physical things in life can trick you right? For example, if you view a red rose in your hand. It is really invisible light waves that your eye picks up, brain translates, and you say "ah red rose". But some other animal might see black and white, mulch-dementional pictures, ultrasound, sonar, etc. Think of those googly eye lizards, who the hell knows what they see. But to them their world is real, just like ours is real. Could there be something beyond the physical?
