Someone had said on another thread, that we have explored more of space, rather than our own oceans.
The
Mariana Trench is an
oceanic trench located in the western
Pacific Ocean, about 200 kilometres (124 mi) east of the
Mariana Islands; it is the
deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,984 ± 25 metres (36,037 ± 82 ft; 6.825 ± 0.016 mi) at the southern end of a small slot-shaped valley in its floor known as the
Challenger Deep.[1] If Mount Everest were placed into the trench at this point, its peak would still be underwater by more than 2 kilometres (1.2 mi).[a]"

It might be shocking to find out, but only
5% of the ocean has been explored and charted by humans. The rest, especially its depths, are still unknown.
oday, we know that the ocean makes up about 71% of the Earth’s surface, and it is the
biggest ecosystem of the planet, holding 99% of all habitable space in the world.
The five main ocean basins, the Pacific, Atlantic, Indian, Arctic and Southern Oceans contain 94% of the world’s wildlife and
97% of all the water on our blue planet.
You would think we should probably concentrate on exploring our oceans rather than space. Who knows what we could find down there....
