    I'm sure most people have seen the movie The Abyss. An intelligent submarine culture able to master technology and water. We don't know if they evolve intelligence there or took it there with them at some point. However why did it take the move to Terra Firma for our technological society to evolve? I mean, if life started in water and thrived there for millions of years before branching out onto land then why didn't or why hasn't an intelligence like our own developed in the deep?

    On a side note let me add: If in fact the majority of planets able to support life in the cosmos are for all intents completely watery or lacking in land above sea level, or without a livable temperature or atmosphere but have had enough time to evolve, then we might be even less likely to contact an technologically intelligent alien civilization assuming technology is the domain of land animals. IOW's intelligent creatures evolving above sea level are the anomaly in the universe.

    Thoughts.....

    All that belongs to human understanding, in this deep ignorance and obscurity, is to be skeptical, or at least cautious; and not to admit of any hypothesis, whatsoever; much less, of any which is supported by no appearance of probability...Hume

    This reminds me of a book published in 1998 by Robert Temple called the Sirius Mystery, which claims to be evidence for aliens dropping in on the Dogon people of Mali.
    These aliens from the Sirius star system are amphibians. They need to live underwater but will surface occasionally. This is not fiction but fact according to Temple.
    https://en.wikipedia.org/wiki/The_Sirius_Mystery

    IMO it's nonsense, and based on ancient myths of underwater gods which found its way into Dogon culture, and probably enhanced by tales from anthropologists.
    It's reasonable to assume that any planet needs oceans, surface land and plate tectonics for intelligent life to evolve. If a planet has only water I don't see how a species could evolve to higher intelligence, which makes our own planet very special.

    An ocean environment is not very conducive to technological development. You're not going to discover fire, or electricity. Unlike the land where plants like trees have to made of materials strong enough to support their weight and thus can be used as building materials, ocean plants can rely on buoyancy and, as a result, are a lot weaker structurally. Little to no free metals would be found to be shaped into tools. The liquid environment tends to produce limbs more designed for propulsion rather than manipulation. Etc.

    It all depends on how strict you decide to be with the definition of technology.

    I do not usually go with the super strict definition that Janus is using.

    I mostly agree with Janus, but offer coral as a potential tool material, and octopi as having potential as a tool using species.

    Octopuses, cuttlefish, dolphins and some smaller fish are all identified by biologists as tool users, its only if one unreasonably narrows the definition to "something involving fire or electricity" that you reach the situation Janus describes.

    Don't forget about birds that use sticks to get grubs.
    Another problem with water breathers in space is the weight of water.

    Why do you make it sound that there is doubt on the evolutionary history of dolphins?

    Also, they are wholly aquatic now, so where they evolved from is moot
