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

Orcas could very well be smarter than us, but it is extremely unlikely they'll ever evolve hands to build tools - it would be a radical and crippling change in their skeleton with absolutely no evolutionary pressure to do so. Primates (and koalas) didn't evolve hands with opposable thumbs to build tools, we did so because our ancestors got pushed into the trees. And orcas really need their flippers to be good in the water.
