Just because people held on to a belief for a long time, that did not make it true, nor was it evidence of any value for the truth of that belief.
For example, the belief the Earth was flat, the belief the earth was the centre of the Solar System, the belief that the stars and planets cause disease (hence "Influenza") or that they control lives etc etc
All those beliefs were held for a long time, and were untrue. Many things have been held to be true, and seem to be, for a long time too, but proof or evidence for the truth or not of a belief comes from testable facts , not the length of time it has been held.
The same goes for the number of people who believe,that is not proof, the kind of people who believe,that is not proof, "Professor Smarty-Pants believes, what do you say to that?" I say "So what? Where is the proof ?".
Those of us who were born in to the WT and were told all our lives what to believe, with no proof, are heartily sick of that kind of dishonest teaching, to maintain that something is true, without proof, is just not good enough.
Evidence, the kind that would satisfy the keenest scientific and forensic minds is required before something can be accepted as true, otherwise it is a mere hypothesis.
You speak airily above Tammy, of a "pile" of proof or evidence.
Would you like to lay that evidence before us please ?
