What Is the Deepest Point in Earth's Oceans?

TL;DR

The deepest point on Earth is Challenger Deep, located in the Mariana Trench, with a maximum depth of approximately 10,984 meters (36,037 feet). This trench, situated in the western Pacific Ocean near Japan, the Philippines, and Papua New Guinea, has only been explored once by a manned craft in 1960. Due to its extreme depths, scientific exploration remains limited and much about this area is still unknown.
