Explain why you are not Protestant in 1 minute

I’m not Protestant because if I was I couldn’t validate what truth is. I have no idea which denomination has the truth. They all say they do, but on their own authority. Name me a Protestant in the first 1000+ years of the Church. You can’t because there aren’t any. And the Bible they use, the one with only 66 books, was not in existence for over 1000 years.
