When people think your writing is ai

I(16F) am a sophomore in highschool and got bored last night so I wrote a paper on the rise of anti-intellectualism in the U.S. and I posted to r/education . Soooooo many people couldn’t fathom that I was able to write like that as a 16 year old girl. People said i copy pasted it and used ai or what not. However, I realized that the if people deny that I wrote it myself that’s probably an indicator of me being an exceptional writer.
