Aliens might not actually be land-based creatures like us. Those who evolved on planets entirely covered by liquid (water or otherwise) might even find the idea of "land" fairly strange.

(It's actually quite interesting to ponder the stages of discovery that liquid-based intelligent aliens might go through. First they might discover air (and land if available) and only after that space as another outer layer. I suppose that adds extra thrill we didn't have. Supposing of course that conditions there allow gas and liquid to exist as separate phases. Planets above criticality would probably be weirder still? Would any bottom rocks under the supercritical fluid still count as land - as opposed to "sea floor"?)

It's hard to evolve technology in water or even a moist environment. Even using fire or metallurgy is already difficult, let alone anything to do with electricity.
