Do not get caught in the dichotomy of either ascribing to conspiracy theories or non-conspiracy theories. Both must be placed on the same plane as far as evidence is concerned. 

Many of both (conspiracy n non-conspiracy theories) are just utter nonsense, yet many of them no matter how unlikely, turned out to be true. 

Just don't get caught in false dichotomies.

"Produce your proof if you are truthful."
