The answer is no, there is no documented case of a person being 8 feet tall. The tallest person ever recorded was Robert Wadlow, who reached a height of 8 feet 11 inches (2.72 meters). He was born in 1918 and passed away in 1940.
The average height for men is around 5 feet 9 inches (1.75 meters), and for women, it's around 5 feet 4 inches (1.63 meters). While there are some people who are exceptionally tall, exceeding 7 feet is extremely rare.
It's important to note that there are conditions that can cause abnormal growth, leading to a person being significantly taller than average. However, even in these cases, reaching 8 feet is highly unlikely.
