Jesus is not the only human in the human history who has been mistaken as God. Some people took Japanese emperor Hirohito as God. Some people say Krishna is God-incarnate, some people say Sai Baba is God.
You and I should not take anyone as God unless we have solid proof of it.
God should be everlasting. Is Jesus everlasting? No. Than a Jesus is not God.
Is emperor Hirohito everlasting? No. Is Krishna everlasting? No. Krishna died. Is Sai Baba everlasting? No. He died. So none of these human beings qualify to be God.
