It seems to me that it is an ancient idea/myth/ truth which some do not acknowledge as fact, in the form discussed here.
Even such widely accepted ideas as plate tectonics are obviously not universally held, or there would be four less threads in the GSD Forum.
Possibly the main difference between a myth and a scientific idea is that latter requires some reasonable evidence, whereas the former can be sustained on faith alone. Of course, this does mean that the scientific idea can change as new evidence is discovered, but such evidence must be open to criticism and honest discussion. Simply shouting “rubbish” by supporters of either side achieves nothing apart from ruffled feathers.
You seem to be saying that when dealing with ancient worlds a degree of guesswork is bound to be involved. I agree, but it is easy for those directly involved in the evolution of ideas to lose sight of that, and believe they are dealing in absolutes.
