With the same reasoning it's never logical to assume that things we can't always identify or put a label on are strange or foreign or from other planets.
The most logical, and most mentally healthy mind, would first try to explore the most plausible explanations and first assume there is no miraculous visitation involved.
If a mountain springs up in the middle of the Pacific and a comic sans message pops up saying LDS is the true religion," I can guarantee it's because the multi-billion dollar corporation called the LDS Church has put money into a new kind of marketing campaign.
And if you're stupid enough to give that corporation 10 percent of your income, maybe you're too stupid to be trying to solve UFO mysteries in the first place.
