create-react was a starter boilerplate for React built and maintained by Facebook. This was when webpack was the standard and just getting a local development environment to "hello world" for React could be challenging.[1]
That project was depreciated and the popularity of the Next.js site framework for react projects (plus I certainly assume heavy lobbying from Vercel) pushed the react docs to officially suggest create-next as the new starting point.[2]
Note that there are many other ways to start a react project and there are also many react projects that don't use or need Nextjs. (I use react quite a bit but I pair it with Astro.js, for example.)
I would say that a lightweight Vite template is really all you need for a lot of early success with a local environment for learning / building with React.
