there are almost definitely sentient, civilization-building aliens out there because we exist and seem to have been created by natural processes. Even if the conditions for complex, multicellular, thinking life to arise are vanishingly small we're still talking about something like 7 septillion stars in the observable universe. There are probably trillions or quadrillions of aliens that at least get to something that could communicate with us. It's more unlikely that we're the first out of however many bazillion instances of thinking life, or that our solar system is the only one perfect enough to host life, than civilizations are just a thing that happens sometimes (however rare it actually is) Unfortunately we'll probably never actually get to meet any aliens because not only are the distances involved way too vast to do anything about, but any two species are probably only capable of mutual communication on a tiny time slice. They're either not at our level yet (animals) or so far beyond us that we might as well be animals and it's entirely possible that aliens like that are out there doing whatever and we can't even perceive them. On the plus side if we ever do go looking it's pretty likely we'd at least get to find some cool alien ruins and derelicts.

How would we know they aren't here already? In the interests of either environmentalism and/or leaving something interesting or useful behind I wouldn't program my von neumanns to use ALL of the mass of a solar system to make more of themselves. It's entirely possible (maybe even likely!) that if we ever get around to exploring the oort we might very well find a handful of probes watching the inner system and sending messages about us home. They might still even be launching probes into other systems. There's zero way we'd be able to detect this right now. e: if they/their propulsion systems are quiet enough (seems likely) they might even be in the asteroid belt. But that's assuming they'd ever want or need to be that close, which is a big assumption one way or another. Pentecoastal Elites fucked around with this message at 20:14 on Feb 24, 2021 |

tacoor gafruf posted:Imagine if the first aliens we meet, Turned out to be just other humans. No special traits or anything, just normal humans. that'd be the most hosed up thing ever and totally change everything we thought about the universe and what life is and how life comes in to being. or that god is actually, literally real. either way it'd be a bigger deal than meeting the most alien aliens you could think of
