Earth
Only Earth has (in our solar system). That's what makes it so special.

Earth is the planet that contains the most abundant amount of water, with about 71% of its surface covered in water. Other planets in our solar system, such as Mars and Venus, have negligible amounts of surface water in comparison.
Earth is the planet with an abundant surface of water, covering about 71% of its surface. This water is primarily found in oceans, rivers, lakes, and ice caps, making Earth unique in the solar system for its extensive bodies of liquid water. While other celestial bodies, like Europa and Enceladus, may have subsurface oceans, only Earth has large quantities of water in liquid form on its surface.
Water is abundant on Earth primarily because of the water cycle, where water evaporates from oceans, lakes, and rivers, condenses into clouds, and falls back to the surface as precipitation. Additionally, the Earth's surface is about 71% covered by water in the form of oceans, which contribute significantly to the abundance of water on our planet.
About 71% of Earth's surface is covered by water, with the majority of this water found in the oceans. This makes water the most abundant natural resource on the planet.
Earth is the only planet known to have liquid water oceans on its surface.
The Earth is sometimes called the "Blue Planet" or "Water Planet" because it is the only known planet that has large amounts of liquid water. Water bridges the gap to life, so water makes it possible for the Earth to support life.
The most abundant form of water on Earth is liquid.
Ocean planets have been hypothesised, where the planet is dominated by water coverage and no land. An exoplanet (a planet in another solar system, orbiting another star) called GJ 1214 b is a possible candidate for an ocean planet.
Earth is often referred to as the unique planet because it is the only known planet in the universe to have liquid water on its surface, which is essential for life as we know it. Additionally, Earth has a diverse range of ecosystems and abundant biodiversity, making it a truly exceptional and habitable place in the solar system.
