That was a serious debate with considerable time, effort, and independant third party scrutiny.

  The 18-hour video debate

  The Rootclaim debate was structured over 3 days with 3 thematic blocks;

  * the first block was about the geographic location and the evidence for the Huanan market versus the Wuhan Institute of virology being where the virus came from

  * the second block was about the SARS-CoV-2 genome and whether its genetic features more likely arose in nature versus gain-of-function research

  * the third block was about probability; how can the evidence be grouped and what probabilistic assumptions should be taken to accurate reflect odds of the evidence occurring

  Each side first got 90 minutes to lay out their cases, then another 90 minutes together to respond to questions. 

  No matter how you slice it, this is a serious effort and time investment, as the preparation alone of materials and research into it probably consumed hundreds of hours from speakers and judges alike.
