Water
The oceans are made of liquid ethane.
Earth is the only planet known to have liquid water oceans on its surface.
There is only one planet known to have significant bodies of liquid water that cover a large portion of its surface, and that is Earth. Other planets in our solar system, like Mars and Europa, have evidence of liquid water in the past or under their surface, but not as extensive as Earth's oceans.
A common name for a mixture made of a liquid is a solution.
Roughly 97% of the world's water is liquid, mainly found in oceans, seas, lakes, and rivers. The remaining 3% is frozen in glaciers and ice caps.

The oceans are made primarily of liquid water. The atmosphere is made primarily of a mixture of gaseous Oxygen (20%) and Nitrogen (80%).
No, The crust is solid. The oceans just happen to sit on top of it.
there were meteorites, a lot of space debris and lightning and liquid water eventually made the oceans.
Earth is the only known planet to have oceans of liquid water.
Yes, it certainly is. All of the above. The air is gas. The oceans are liquid. The ground is solid.
Because its rocks clearly show that it once had oceans made of liquid water.
Earth is the only planet known to have liquid water oceans on its surface.
Atlantic Ocean
Assuming the Oceans are of liquid water, the only provable place where they are found is Earth.
Under-GROUND oceans? Probably not; the current estimates for Europa indicate that the surface is probably ice, with perhaps oceans beneath the ice. If the oceans are made of water rather than some more exotic liquid, then there's at least a possibility that life might exist in that ocean.
