^^ Again, I understand. But there is a big difference between "What made this", and " Looky here, Bigfoot tracks!!" One is making a fantastic claim, the other is not. One could be investigated and possible explanations provided. The other is a point that some people refuse to move from, even when plenty of reasonable, and more likely, scenarios are presented.
And science has no obligation to go and respond to the "Looky here, Bigfoot tracks!!" claim. The person making that claim takes the burden onto themselves the second they utter the phrase. The first one, though, there you have something worthwhile. It's a puzzle asking someone to solve it. Sometimes this, rather obvious, nuance gets lost when discussing Bigfoot and people start to think that just because I said something is evidence of Bigfoot it will remain so until Science proves it otherwise. But that's not how it works. Footers will claim something is a Bigfoot ( blobsquatch), or tracks were made by Bigfoot, and they move forward completely ignoring rational, alternate explanations for the evidence. And then they wonder why Science is not that interested in chasing these down and arguing with them anymore. When you start by claiming something is a Bigfoot, then you started off on the wrong foot in my opinion ( pun sort of intended).
