In 1991, what name was given to the Iceman, a three-thousand-year-old natural mummy discovered in the Alps?

Tsetsa💜, when you add our current year (2023) to the estimated year he died you end up with over 5000 years.

3000 years ? I've been told numerous times in documentaries that he's 5000 years old, i guess it was wrong estimation back then.
