I imagine that a few centuries ago a RationalWiki page on microorganisms would describe them as: “A pseudoscientific belief that human diseases are caused by invisible beings. Coincidentally, exactly the same thing as described in the Bible. This dangerous myth is spread by opponents of scientific bloodletting and other uneducated people.”
Microorganisms do not have to make any special effort to hide themselves (at least not from human beings, if they may do some hiding from certain other microelements of humans).
Likewise, if you propose a theory of aliens which does not involve hiding from humans, e.g. there are aliens, but too distant to be visible to us, that theory will be reasonable. The hiding theory is not.
