George Mallory of England.

Mallory was a great English explorer who died while trying to climb Mount Everest. When asked why he wanted to climb Mount Everest, he replied, "Because it is there. ’’ （“Because it’s there! ") has become a famous saying that people often quote so far.

In p>1922, Mallory failed to challenge Mount Everest from the north slope for the first time. Two years later, he and his teammate Andrew Irving tried to climb the summit again, and they never came back. The dispute about whether they had climbed the summit before their death became a famous "Ma 'ou mystery" in mountaineering history.

If it can be proved that they did climb the summit before their lives, it will change the history of Mount Everest, and this climb will be the first time to conquer Mount Everest in human history.

Extended information:

Most mountaineering historians believe that Mallory and Irving have little chance of successfully reaching the summit. First of all, according to modern standards, the mountaineering equipment in 1924 was almost primitive.

Secondly, Mallory's artificial oxygen can only last for eight to ten hours at most, which is only half of the time needed for the whole process. In addition, The Second Step, the last natural hazard before the summit, has not found any artificial relics such as ropes, so it is almost impossible to climb the second step by hand.

Finally, Mallory didn't have enough daylight time. After reaching the summit, he was able to cross the most steep ridge of Mount Everest and return to his final resting place.
