This is one of those things where an objective person shouldn't start out with a completely neutral attitude. Have you ever heard that phrase "Extraordinary claims require extraordinary evidence"?
For example, If I take a blurry photo of something I see outside on a full moon that's probably a raccoon and proclaim its a photo of the elder god Nug, spawn of Azathoth, the Lord of All Things, and someone points out that its probably a raccoon but the photo is so bad there's really no way to ever tell the right attitude isn't to say:
"It can be compelling and attractive to fill the silence or the unknown with an invention of certainty - sort of like a prophet or shepheard - but the edge of known demands more curiosity and wonder for an honest approach."
Great Old Ones and beings from the ultimate void can be blurry in photos from the ionization of air around their bodies as they attempt to synchronize their quantum spin states with our normal universe. But it’s not just like a blurry photo. Usually you see some ionization glow of the right color for nitrogen and oxygen emission lines.
This is even more true when there are so many blurry photos. It's as if Nugs acolytes keep putting up photos and making claims but not a single photo clearly shows his three heads or single pogo stick leg. The more photos there are, the more likely it is that at least one of them should clearly display Nug.
