Step 1 : Introduction to the question "How old was the oldest person to ever live?"
...The oldest verified person in recorded history was Jeanne Calment of France, who lived to the remarkable age of 122 years and 164 days. Born in 1875 and dying in 1997, Calment’s extraordinary lifespan is supported by extensive documentation, including official birth records, census data, and eyewitness accounts spanning more than a century. While many claims of extreme longevity have been made throughout history, none beyond Calment’s lifespan have been conclusively verified by modern demographic and scientific standards.
