I go with science every time until it's proved otherwise; If it walks like a duck, sounds like a duck and looks like a duck you can bet it's a duck.No matter what you do or where you go in life you have to go with the most educated and wisest opinion because if you don't you are accepting amateurism.
For an example if you look back to the smallpox epedemics of several hundred years ago, if somebody had said at that time you need a very small dose of it to become immune you most probably would not have believed it.It took intelligent research to come up with immunization and become accepted.I wonder how many crazy cures were going around way back when.
That is precisely what is wrong with the JWs argument when they try to persuade people not to go for higher education and I say if you don't dig deep enough you want learn the truth.
In reply to the original question the answer is no because they woud not be here now. What the heck are speleotherms ?
See you later I'm off to find a caving club. I'm going underground for awhile.
