Yes, to some extent. But my comment about "speculation and drug induced visions" was not aimed at believers, as such, but at the preachers and church leaders who determine what a particular faith actually involves.
There has been scientific study, and some evidence, regarding the propensity for the human mind to accept the supernatural, as a survival mechanism. (See here about this, too.) So believing in the supernatural is apparently the way we are wired. But when we have evidence which counters the supernatural, such as the mechanisms of weather, or the actions of volcanoes, holding to these superstitions would seem to me to be surrendering your reason in favor of fantasy.
After all, we no longer believe that Vulcan works at his mighty forge beneath Mt. Etna, do we? We no longer feel the need to place coins on the eyes of the dead to pay the ferryman on their journey, do we? So why must we hold so tenaciously to the myths of Yahweh, or Allah, or any other gods?
