If the Earth is more than 70% water, then how come the most intelligent life forms are on land?

@Mondayschild How do you know we're not?

@Dobsdobs We have neglected to study the ocean in any real depth (pardon the pun). as opposed to space exploration. We have no clue what we would find there as far as intelligence.

@Mondayschild True! But if there is true intelligence in the ocean's depths that we have not explored so far, then they that life form must have explored us. Logically, if at our level of intelligecne we can explore the ocean as mcuh as we have done, then at a similar level of intelligence a deep ocean specis can explore outside the oceans just as much. So why has there been no contact. And is the absence of contact proof of absence?
Or is the deep ocean species way more intelligent than us and has already explored our realm in a way that we have not een found out?

that was a lovely pun, by d way
