Credit where it's due, I told you to try again and you did. Yes actually the idea that a bunch of people who have heard stories about a thing convince themselves that they've seen the thing is entirely plausible and in fact entirely scientifically verified, claiming otherwise doesn't help your credibility.

Get your eyes checked
