Yeah exactly. It’s not an unreasonable search and we don’t have confidence our search methods work. Hell, the Ryugu sample was contaminated while in a hermetically sealed clean room filled with nitrogen gas. Either the blood brain barrier is even more effective or maybe the story isn’t quite so clear. This is not an unreasonable hypothesis nor do have we exhausted search. Hell, we’re literally talking about it in response to a related find in another species. So it’s definitely not a wild theory or one that conflicts with known theories.

The chocolate teapot example is a non sequiter as it fails both Occam’s razor and the principle that extraordinary claims require extraordinary evidence not to mention that it wouldn’t follow any laws of known science and it’s existence very well would upend quite a few of those. The scientific method isn’t something you get to apply piecemeal.
