You originally made the point that we did land on the moon, and there are no lizard people, as if it's obvious, and how dare people think otherwise. This is not the sane approach of critical thinking.

The sane approach is to always begin with the simpler default which does not require blind faith on the matter or trusting whoever you consider to be your authority. In this instance, the simpler default is that we did not go to the moon, and there are no lizard people till proven otherwise. Both of these require considerable proof to stray from the default.

If you are satisfied that we went to the moon or that there are lizard people given the proof you have seen, that is fine. However, the default should not be that the monumental task of going to the moon occurred or that super rare creatures exist if you cannot independently verify the information for yourself.

Given this, if your research on the topic has convinced you, you should not be faulting others for choosing the sane default who are unaware of the rare proof you have gathered. To put it differently, it should not be taken as obvious that we went to moon, or that lizard people exist.

Your original point that it makes more sense to assume there are no lizard people or that Joe Biden hasn't been replaced by a look alike are reasonable assumptions. However, it is not reasonable to just assume we went to the Moon because NASA says we did, and you should not be faulting people who want proof on the matter.
