We can certainly be open to all hypotheses, especially if theoretical physics becomes stagnant.

But the phenomenon of pareidolia gives us some reason to doubt our personifications. As Daniel Dennett explains, we're exceptional pattern detectors, and we can overuse that skill, seeing boogeymen where there are none. We can find meaningful patterns in the clouds or in the tea leaves if we set out to find them, because that's our social instinct: to find other people and to socialize with them. Even infants do it.
