Unforunately Simon Parkes is part of the Qanon movement where they mix 10% truth with 90% lies and cleverly package it up to seem like its truth. Parkes is a known liar and I wouldn't trust anything he says, he like the rest of the Qanon movement, make money from views/clicks on their YT channels and what not, Parkes is hardly a reputable source, he is just a charlatan.
The best place to start for the Ring Makers would be the book as mentioned by Hans Baumann Jr...
The book can be downloaded for free, if you look hard enough, its called "Ringmakers of Saturn" by Norman R. Bergrun.
