I will believe anything that has sufficient evidence to believe it is true or likely true. I am skeptical of your claim, but not closed minded.
You believe that this is true, why do you believe it?
If I don’t have any reason to believe it, or in other words, I’ve seen no evidence that leads me to believe it is true, how could I tell you what would prove it? It just seems like you’re trying to shift the burden of proof to me, but you’re the one claiming it is true.
