They call me a man but I'll never have a wife i was given a body but not a life they made me a mouth but didnt give me breath water gives me life sun gives me death WHAT AM I?

You are a "scarecrow." Scarecrows are often depicted as human-like figures made of straw, placed in fields to deter birds. They have a body and a mouth but lack the ability to live, breathe, or experience life like a person. The phrase about water giving life and the sun bringing death refers to the scarecrow's role in relation to the crops it protects.
