The reason I have a serious problem with the ETH is the fact that it does fit the culturally relevant pattern of transient historic paranormal influence in an exceptionally fit manner.
Still in yet, this does not seem to in any way negate the ETH, as much as it reeks of a singular intelligence, rather than many, that ultimately consists of an informational non-materially bound volition.
So, ultimately, if such an intelligence requires no physicality to transition from one point in our HDST (hyper dimensional space time) to another, a "planet" may not equate to the accurate origin of such a non-human sentient volition.
I could be WAY wrong. I don't have any real certainty whatsoever. I just intuitively have a very hard time with the whole "Disneyland of The Gods" notion from a humanoid encounter stand point. I think there is tremendous value in these reports and cannot thank the diligent efforts of those like Albert S. Rosales enough.

IMO, these reports bear out a tremendous value with respect to possible evidence for an alternate perspective of responsible causation.
