Best Answer: man has been ALMOST to the deepest point in the sea Most parts of the ocean are about 5 kilometers (3 miles) deep. However, deep ocean trenches can be as much as 11 km (7 miles) deep. The deepest point in the world's oceans is the Challenger Deep, in the Marianas Trench; its depth is 11.03 km (36,200 feet). In 1953, the bathyscaphe (bathy = deep, scaphe = ship) Trieste descended to 35,800 ft (10.91 km) in the Challenger Deep.
