Well he was a human , Concept of God is very different , If you believe in God then every human has some sort of god in him , He invokes godliness by good deeds.
Why to nitpick how long he lived or if he said so or not .. He achived what many others could not do in hundreds of years like a Multispeciality hospital in Puttaparthi and in Whitefield Bangalore which provide free treatment to poor , Krishna river water to Chennai city at cost of 600 crore , Educational institutes and water to Villages around puttaparthi.
