I think this can be compared to the way really old UFO photos are treated by believers. The Trent photos are a great example. Believers often treat old photos as "better evidence", claiming that the technology needed to fake them didn't exist back when they were taken. They're right that Photoshop didn't exist and that analog photography had certain limitations when it came to methods of faking photos. But they chose to forget that, at the end of the day, none of this really matters. Faking the Trent photos wouldn't have required Photoshop or any advanced digital technology. All that was needed was a model and some fishing line. And the same goes for the PG film. A gorilla suit and some experimentation with posture and gait are really all that would have been needed, since both the proportions and the way the figure walks are consistent with a human in a costume. But it's the same old argument: "It's an old photo/video, therefore it must be real."
