I'm not making an argument from ignorance. I'm making an argument based on observation. For instance I observe an
alchemical crop circle, and I argue that if so then the circlemaker has alchemical knowledge. So if a team of circlemakers made it, then at least one of them must have some alchemical knowledge. Right?
Was such obscure knowledge "easily" available to find on the internet in 1991? Or would a less quick and superficial level of alchemical familiarity be required? Maybe a level of expertise?
