Okay, you keep setting yourself up,
You say forum rules, (who knew you were the forum cop, it does make more sense than your rambling) demand support for contentions, support has been given for the beliefs of those who started and posted to this thread whether it meets your standard or not, since we are discussing beliefs, there is no need for absolute proof.
I am glad you conceded that beliefs are not based on proofs, facts do not require belief, therefore beliefs, or contentions as you label them here, are not dependent on absolute proof.
Now, as I said elsewhere, either offer proof that meets a scientific standard that it's absolutely without doubt impossible, or stfu.
Destroy the belief if you can.
You are like a child in a lab predicting results before the experiment even gets started.
People believe it, you can't prove definitively they are wrong, until you can stfu.
