An Asian man is praying at a Buddhist temple.
The man has been Buddhist his whole life.
Just because an Asian man is seen praying at a Buddhist temple doesn't mean he is actually a Buddhist and even if he is one prayer doesn't imply a whole life time of practicing the faith.
It is not necessary that a man praying at a Buddhist temple be a Buddhist his whole life.
An Asian man praying at a Buddhist temple doesn't imply that the man is Buddhist.
