It would still have oceans but no atmospheric water in Earth if no icy debris had arrived.

A. It would still have oceans but no atmospheric water.

Explanation:

Seas characterize our home planet, covering most of the Earth's surface and driving the water cycle that commands our territory and climate.

It would in any case have seas yet no air water on Earth if no frigid flotsam and jetsam had shown up. For a long time, it was accepted that the frosty moons were only that - solidified husks, strong to their center. However, lately that thought has steadily been supplanted by a fresher, additionally energizing worldview.
