"...the placebo effect is typically pooh-poohed and waved aside, denounced regularly by skeptics, scientists etc as 'magical thinking', 'selective thinking', 'self-deception', 'wishful thinking', 'fallacy'."
Not true at all. Scientists and skeptics are great believers in the existence, and power, of the placebo effect. In fact, many skeptics think that a lot of phenomena that others might explain with "magical thinking" are truly the result of the powerful placebo effect.

Ivor asks
"...what is the proof of that creator's efforts and existence?"
Answer: none.
How would you test for the existence of the creator? What set of measurements could one make to prove this existence? I can't think of any, so the existence (or not) of a creator, properly placed (for example before the Big Bang), does not conflict with my desire to test all things testable, and form my beliefs around the results.
