Understanding and updating beliefs on deeply engrained topics can take enormous efforts, but sometimes it can be so hard that the listener cannot even in principle accept the new reality. The listener is simply not ready, he lacks a vast background of reasoning leading to the new understanding.
What fact that you know is true but most people aren't ready to accept it?
By "you know is true" I really mean "you are very confident to be true".
I wouldn't say I know it to be true, but read and reviewed books by experts (anthropologists, special effects experts, pro and con) and ended up concluding that bigfoot probably exists (~75%).
I wrote up my rationale in r/slatestarcodex a year or so ago:
It's discussed in the Reddit comments, if you want more details, but briefly: A rare species with a long life might leave on the order of ~100 dead a year. If each corpse has, say 1e-5 chance (low but still plausible number) of being found by a person, then it could take a while.
I don't know of any claim that they would take care of their dead, but I don't see that as implausible.

If they exist, then they would have crossed the Bering land bridge at the same time as humans. They would never have lived anywhere without a human presence. And yes, similar sightings are known from across Asia also.
