The problem is that science cannot prove a negative. They can only produce evidence that, to the best of their knowledge, it appears that people weren't flying, but there will always be additional questions at every level. Soon enough the research will run out of answers.

I.E. "Well, do you have records of every region of Malaysia during that time? What about every family? Maybe it was passed down in just one lineage. Can you show me the evidence you collected on every single Malay? Maybe it was just one person."

When dealing with people making obscene claims, the only sensible way forward is to require them to produce evidence of their claims or get off the proverbial stage.

Nothing is really proven in history. Story is right there in the name. Now there is overwhelming evidence for certain stories over others. And I agree the university is free to terminate researchers that don’t align with the desired messages of their donors. Academics do not need to be in consensus - and in fact that’s an unhealthy state for them to be in.
