I'm not saying that the speaker is laughable. And I have no prejudice against the Chinese. Nor do I think the speaker is lying. I think you just don't understand the meaning of what he is saying, because you lack context. I actually read more on this particular interview in the past and the explanation for this soundbite in full context was quite reasonable, but it would take me some time to find it again.

You're weighing the evidence in a laughable manner: you have a "soundbite" from a single scientist, and it is easily misconstrued: the meaning would depend on the context of the conversation and you're weighting that one sound bite higher than 100,000 scientific results.

And your idea that all these scientific papers are just "computer manipulation" is purely paranoia. Here's just a few such papers, published on many different sites for scientific research:

I could go on all day finding articles like this. But you go on believing you understand a single soundbite to mean they are all fake...
