On the Nmap home page in my language, I can see -sP scan, but on the English version of the site, I can't see it. But I see -sn that looks very similar, I want to understand what's the difference.

There is no difference. To quote man nmap:

In previous releases of Nmap, -sn was known as -sP.

    Many of the man page translations are very out-of-date. Nmap still understands -sP, but the documentation has switched to -sn (no port scan) in order to match -Pn (no host discovery) and -n (no reverse-DNS name resolution). Aug 13, 2019 at 3:25
