Tiny nit at 5:38: "[...] organic compounds are the basic chemicals from which life forms". That is only true for the kind of life we have encountered yet. There could exist life forms based on things other than organic chemicals -- we just haven't encountered it yet. But I'm sure you already know that!
I just think it's a bit sad that many science videos/shows/texts/... (even the really good ones, like your channel) often seem to imply that life requires organic matter. It's a tiny thing, but I would prefer if everyone would just add "[life] as we know it".
Otherwise great video, as usual!
