How was the first yogurt made?

Question

I went on a spiral of homemade yogurt videos. But what I noticed was the common step in all of these videos is to add a dollop of existing yogurt to inoculate the new one. But how was the original yogurt made? Please explain. Thank you!

I know this is about cheese but I find it interesting how the first cheese might have been created. [Callu de cabrettu](https://www.atlasobscura.com/foods/callu-de-cabrettu). This could be done even before the domestication of milk producing animals.
