Oh, I watched the video. Two people generating straw man after straw man and destroying their own feeble premises together does not a good argument make.

As for my absolute claims, non-belief is the default stance. Atheism is, and has to be, the starting point. As the one guy said, if one were to claim fairies exist, the default stance to take on that is one of non-belief. "Awesome, prove to me that your fairies exist. Set up a camera, a sensor, a fairy-trap and lets confirm that."

Same with all the deities and belief systems in the world. You are welcome to claim an Allah, or Zeus, or Loki and Ra. The logical default is one of non-belief to these claims until data can show otherwise.

If anything, I feel bad for the one guy. I hope he joined a moderate sect of Islam that doesn't punish apostasy when he eventually changes his mind.

Have a wonderful day!
