Mount everest was still as high before it was discovered

The question that almost everyone answers incorrectly
The question that almost everyone answers incorrectly:

Mount Everest's elevation is 29,035 feet (8850 meters).

Most people don't realize the hightest mountain in the world is Mauna Loa in the Hawaiian Islands: 56,080 ft (17,170 meters).

Mauna Loa is a REALLY tall and big mountain. At 60 miles long and 30 miles wide, it makes up half of the entire island. When one considers that the flanks of Mauna Loa sit on sea floor that is about 16,400 ft (5,000 M) deep, the "height" of this volcano relative to neighboring land (the sea floor) is more like 30,080 ft (9,170 m)! Mauna Loa is the largest active volcano in the world. In fact, using this last measure of its height, it is one of the tallest mountain in the world (although many mountains, such as Mt. Everest in the Himalaya mountain range, sit higher relative to sea level). All large land masses (such as mountains) also push down upon the Earth's crust due to their enormous weight. So, directly beneath Mauna Loa, the sea floor on which it sits is depressed by and additional 26,000 ft (8000 m). Thus, if one wanted to say how thick (at its center) is the lava pile that makes up Mauna Loa, one would need to add its above sea level height, its sea floor to sea level height, and the thickness of its depression in the Pacific sea floor. These total 56,080 ft (17,170 m). For more details about estimation of the actual thickness of Mauna Loa volcano, see the write up on "How high is Mauna Loa volcano" at the HVO website.

Most of us human types only look at the 'surface' when considering 'height' and most everything else, so 'above sea level' becomes our standard. Mountain climbers don't look at Mauna Loa like they do Mt Everest, and there's good reason. Nobody attempts to climb mountains starting from the sea floor. LOL
