Kat, you react as if even the mere information about potential dangers was a threat to your beliefs.

everything has to have an explanation before one can believe in it working.

You got completely wrong. That's neither my position nor standard anywhere in science. To have a working explanation or a theory for an effect is preferable to have none for a lot of reasons, but a reliable fact remains a fact even without explanation.

What truly separates science from belief systems is something else, namely the demand that something has to be shown to work before believing.
