But for the other cases, let's say bone-like, it's an anomaly because it looks like bone where bones shouldn't exist. "don't assume bone looking thing is pareidolia" can't work cos it's saying "don't assume pareidolia is pareidolia".
I think I get you. In the case of the Face on Mars, better photos later showed that it was NOT an artificial creation, therefore it WAS a case of pareidolia. In the case of the bones, according to the authors line of reasoning as I understand it, there is no other photos to show they are NOT bones; therefore, we should not assume pareidolia because they might really be bones.
Fair enough, but as I noted upstream, this is just one little piece of a larger paper trying to make the argument we should take the authors central premise seriously. Their claim is that UAP are real and unexplainable as mundane encounters. A likely explanation is aliens, something they have claimed in other papers.
But here they're claiming aliens are not zipping in from distant star systems in FTL starships. Rather, they have been here for a long time and MIGHT be hiding in plain site amongst us.
Or the aliens are time traveling future humans, so not really aliens.
Or the aliens are an unknown lineage of other intelligent hominids or other species that evolved before us, so not really aliens.
Or the aliens are hiding in the oceans.
Or the aliens are elves and fairy folk. Seriously.
Or aliens are living in a hollow earth.
Or aliens are hiding out, or previously hid out, on the moon and Mars. This is where the pareidolia argument comes in. The author's claim is that all of the above listed explanations are just as likely, if not more likely, to explain UAPs as any other explanation. I would disagree.
As for the pareidolia and the bones, I would argue: 1. All exploration of Mars has shown negative results for life now, or in the past, especially for a large technically advanced civilization. This may change in the future, though I suspect there will not be any signs of an advanced intelligence ever found. 2. We know pareidolia is a real phenomenon and that surface of Mars has a history of producing various pareidolia events, from the Canals on Mars to the Face on Mars, which turned out to in fact be cases of pareidolia.
So, the prudent thing at this time is to say the bones are
likely a case of pareidolia.
As noted above and in the other thread, the authors seek to troll out every conceivable theory about UAPs, including aliens on Mars, and then turn the burden of proof around by claiming that unless their presented theories can be DISPROVEN, they are just as likely to be true. That is, until someone PROVES the bones on Mars are NOT bones, we cannot assume pareidolia because they might really be bones. I would disagree.
