It feels like talking about religion. In a lot of them at the very least, there is an almighty, omniscient god, the alpha, the everyday, and the omega god, the one that maximizes knowledge, intelligence, power, whatever. And people following that religion know exactly how that entity thinks and behave. Because that entity should think like humans of the current culture does, no?<p>With aliens, with a different culture, civilization if that concept applies, language or not, and enough technology to make interstellar travel, and all of that for thousands to millions of years, those aliens that are far beyond our imagination, well, somewhat we know how they think and should behave, now knowing the technology they should have, the knowledge about the universe they should have, philosophy or whatever.<p>We don't even know if it will be ever practical interstellar travel, because we didn't reach that stage yet. In theory it should work... in theory I could climb stairs till reaching the moon too. People is too busy trying to figure out how advanced aliens should think, and didn't stopped to analyze how they are thinking.
