The difference between the Mount Sinai situation and the stories of revelations among the nations – continued

Thank you Rabbi for the response, but I still have a difficulty. When there are millions of people in a nation with a variety of opinions that have been cultivated over the generations, will a person arise and claim something that apparently does not match the majority of opinions – will his narrative prevail? Although there are a variety of halachic disputes, on the issue of the number of people, the narrative prevailed until, over the generations that followed, there were no disputes about it? (To the point that it was written in detail in the Torah).
In the stories of the righteous, it can be argued that they will undergo adaptation because the witnesses to them are few and sometimes the miracles are described as something that is easy to mistake and illustrate. It can also be said that the narrative already shared by those people is what convinced them, but in the AMI there were other opinions that they did not accept and shared, contrary to the matter of quantity that everyone agreed on despite the narrative of preserving tradition. Thank you very much again!
