Who was the oldest person who ever lived?
user
People are living longer than they have in all of human history.  If you look back into the distant past and count up the years of a person’s life, then the earliest life expectancy ever was probably about thirty years.  If we follow the average lifespan trends, then I think the person who lived the longest, more than 120 years, was probably Jeanne Calment of France, who died in 1997 at the age of 122.

I will! 
I want to emphasize that the answer was incorrect, because the oldest person ever was Jeanne Calment.
