The ocean?
Earth's largest bodies of saltwater are the oceans. The five major oceans are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean, and the Arctic Ocean. They cover about 71% of the Earth's surface and hold about 97% of the Earth's water supply.

There is a lot of water on earth. The ocean is just a huge basin that hold all of it. Only the highest land can escape from the water and become what is now known as dry land
Sponges are only a small part of the ocean's biodiversity, so the amount of water in the ocean would remain virtually unchanged if they didn't exist. Sponges primarily filter and recycle nutrients in the water, but their absence wouldn't significantly impact the overall volume of water in the ocean.
common questions about the ocean are: What animals live in the ocean? How much water does the ocean hold? why are there 4 or 5 different oceans, why not just one big one?
Yes, gravity plays a significant role in holding water on Earth. Gravity pulls all objects towards the center of the planet, including water, which causes it to collect in oceans, lakes, and rivers rather than floating off into space.
