Drop some ice cubes in a glass of water and when they melt, the water is at almost the same level as when you put them in the water.

That only works for ice that's already in the water, such as icebergs.

We've got millions of square miles of ice piled up on land surfaces, though. If that were all to melt, it would definitely raise sea levels, because it would add to the amount of water in the oceans. But, how much it would raise it, I don't know.

not only millions of acres of ice, but also underground aquifer freshwater, and, of course, given that God is God, any or all of the water of other planets if He chose to use it.
