Yes, that is what I was saying earlier. It is interesting that we accept that the burden of proof is on the one who claims something exists to demonstrate it existence. We don’t allow somebody to say XYZ exists and if you can’t disprove me then it shows I am right.
I don’t know who established this rule, but it seems like a very logical and rational rule that is at the basis of science and all the technological progress that has been made. Possibly in earlier times, the burden was on those who did not accept the claim to be forced to disprove.
BTW, I resent the earlier email.
