Not to change the subject to much But we haven't really explored our own oceans yet If not having the knowledge of our own under water world how are we supposed to start life on another planet that is completely covered by it?
Water or ice? Liquid or slushy or frozen solid? Ever since the Voyager spacecraft missions flew through the Jupiter system in 1979, planetary scientists have wondered about the layer of ice surrounding the second moon of Jupiter.
Europa's ice surface makes it one of the brightest, and smoothest, objects in our solar system.
Recent Galileo spacecraft images have provided evidence that Europa had a liquid ocean underneath the frozen crust sometime in its history, but it is not clear if this ocean still exists. Of the various explanations proposed by scientists, most scenarios of Europa's evolution have the water layer freezing solid earlier in its history. The moon's surface is -260° F, which could freeze an ocean over several million years. But scientists think that the warming caused by a tidal tug of war with Jupiter and neighboring moons could be keeping large parts of the ocean liquid.

We may have had a thread like this before but.....
Hold it?I will never let this one go
