So I found the video in question and watched it (full 30 minutes). Skip to the end to see the relevant parts for anyone reading this:

As for this:
> Youtuber Smarter Every Day released a video yesterday that appears designed to spread misinformation on creationism.
I dont get what you mean here. He spread no information about creationism at all, let alone misinformation. He stated that this is a focal point for those who argue creationism vs evolution but otherwise did nothing to actively promote either viewpoint, in fact rather the opposite, he suggested people stop taking absolute sides and to form nuanced opinions.
Honestly his take seemed far more honest and lacking in disinformation than usual.
