If life evolves on a planet with only oceans, no surface, imagine how much longer it would take to discover rockets that can leave the planet.

Like if there was no surface on earth, and only fish, there must be some very significant reason for advanced fish to even want to leave the water, let alone the atmosphere

I wonder how oceanic life would be able to record information. If we assume that extraterrestrial oceans would have lifeforms similar to corals and barnacles, how would an aquatic civilization prevent written information from getting encrusted with biofouling or keep it from corroding away?

there are so many ways to record things... for example https://en.m.wikipedia.org/wiki/Quipu maybe the need to keep it clean just makes it more important to a society...
