Can someone explain what this kind of comment is meant to be and what is the history behind it? It looks grammatically incorrect, and I can't reorder the words to make sense either.
I feel there might be intelligent species out there without either the resources to develop technology or the ability to do so. Sharks could become smarter than us one day, but without thumbs they aren't going to succeed in overtaking the planet. Similarly, there could be a humanoid fish species under thick ice sheets of Europa, and they would never guess there is anything more than their "ocean" in the universe.
