I just use my skills at googling

lmao okay

To add to WhatWouldKarlDo's posts, which provided credible counter-evidence (A CBS reporter on location, and a Latin American diplomat's leaked eyewitness account), I want to further emphasise that using a search engine to assess credibility and provide ethos isn't a strong argument. If I search your username, and if you search mine, neither of us will show up as a real person and both our histories will show we reply to political topics. Should we therefore conclude we're both just writing propaganda, and further assume that makes it false?

We're writing opinions or analyses, and hopefully, substantiating them with evidence. And surely the book is doing the same.

See my edit. But here's the thing. We have video of the moon landing and rocks from the actual moon. That's solid evidence. We have plenty of evidence of the atom existing, because half our tech wouldn't work if they didn't exist.

Where is the evidence of a massacre at tiananmen square? Please read the links I gave you.

Edit: please remember, you said that this was an easily disprovable conspiracy theory.
