The lowest point on Earth is the Challenger Deep, located in the Mariana Trench in the Pacific Ocean. It reaches a depth of approximately 10,902 to 10,929 meters (35,768 to 35,856 feet) below sea level.

It's worth noting that the exact depth is still being refined, as different measurements have yielded slightly different results. However, Challenger Deep remains the deepest known point in the Earth's oceans.
