No I'm positing that skill(education) is needed by humans..
But wisdom should be the bar sought after.. I thought I said that..
What is wisdom anyway?.. More important question than "what makes this or that work"..
The Difference between a Tinkerer.. and Sage.. even though a Sage might appreciate a good Cabernet and/or a hot tub.. maintained by a tinkerer.. or a tinkerer the wise counsel of the Sage.. The metaphorical difference between the two is immense.. Thats what I thought I said or implied..
I've known rich people that were poor and poor people that were rich.. and tinkerers that were Sages and Sages that were tinkerers... i.e. Scientist/Engineer = tinkerer.. Sage = possessor of wisdom..
I'm sorry, I think we've run rather far afield of the original point, then.
The point being, people 2000 years ago were even more easily fooled by hucksters claiming to have miraculous powers than people today. Because we are, on average, more educated.
And since I see that people today still are amazingly easy to fool (David Koresh, Jim Jones, etc), then the odds are that back then, people were even easier to fool.
So I'd say it is wisdom to take any such claims with a grain of salt.
