To those who believe, no explanation is needed, to those who do not, none will suffice.
I've never seen it done. I've never tried it. Not sure what I believe. But, I would have to see it to believe it. I think the one question most of us who are agnostic on the subject have is, if you can hold a couple of rods and find gold, why are you not a billionaire? If you can find water, why are there so many dry places in the world?
I am trying to honest here, not calling anyone out. I'll maintain an open mind until I have more evidence.
