Sometime back I read an article that proposed that the lack of water on other planets compared to the huge amount on Earth implies that Earth may have been impacted by a Ceres-like planetoid (lots of water in the makeup) or meteor a long time ago.

Not unreasonable I suppose ...

Mars-sized.

Being water-rich or not is irrelevant, according to the Theia-impact theory.
