Special is a relative term. As wonderful as the human brain undoubtedly is, I don't see that it should be special as in able to tap into previously inaccessible energies. It's just another arrangement of fundamental matter at heart, and in that at least it is not special.
Naomi -- my principal question was more general, really, which was, "What are your criteria in general for assessing the credibility of any claim?" So far, for example, I've laid on the table the history of scientific evidence that doesn't support this, that has been rejected on the grounds that "parapsychology is a truly random phenomenon" or that "we don't have the technology yet". Leaving aside the fact that investigating the random is basically all of what modern Science is anyway, the second criticism is not impossible, but serious parapsychological scientists exist and do not agree with you and have tried the world over to investigate this, with results indistinguishable from statistical noise. Never mind, because the anecdotal evidence is highly convincing. Or, similarly, there may be plenty of artistic and archaeological evidence for some alien visitors, but such is open to interpretation and there is nothing beyond this.
So while my hierarchy of evidence is experimental followed by everything else, yours would appear to put other evidence on an equal footing with experiment. Is this a fair assessment?
