I do not remember saying the multiple methods "were" erroneous; I said "if," a hypothetical. And if pigs could fly (hypothetically), they'd make great pets.
Either you have evidence that the methods are erroneous, or you don't.
If you do, post them.
If you don't, why did you bring it up? It makes as much sense as my bring up flying pigs.
Because you stated it as though having multiple independent methods would, incontrovertably, seal your argument for the age of the universe. I was simply pointing out that that is not necessarily the case. Do you agree or not?
