I wonder whether that is a correct use of the word or a kind of 'Japanglish'.
My questions are:
(1) For example, "I am a creator of that poster." is natural sentence. Right?
(2) If someone says "I am a Creator." when he introduce himself in English, are you think it's strange?
(3) "I am a creator" never means "I am God", does it? (I know "the Creator" means God.)
Is my understanding correct?
