Do aliens exist? By the number of star systems that are out the that have planets in the habitable zone of the parent star the answer is yes. Even if ( which we most certainly are ) we are a rare anomaly, that would still leave us with millions of intelligent civilizations out there. Not saying it’s common, just saying by the number of stars and galaxies out there it’s pretty much a must.
Why don’t they make contact? Because there’s no reason. If they have progressed enough to overcome the challenge of FTL travel it is also likely that they have also progressed past the need for war, slavery and definitely any fossil fuels or elements. So why would they? The best guess I can come up with is 1. We are a seed planet, an experiment and they are pretty much leaving us B just occasionally checking in to sample or check on progress. Or 2. Have you ever observed a child learning a new task and seen them figure out a completely different way to complete it which may be better or more effective that the original? Well that may be it , they may just be observing us to see if they can learn anything new.
Advanced civilizations have no use of us in the end other than curiosity and also it’s more than likely they’ve transcended their own mortality, which means the first alien sighting from thousands of years ago could be the same group of space dudes we claim to see today. Just my take.
I never understand someone like Basiles view that theories of aliens is crazy Just think about humans for a moment, we can already alter dna and make custom babies, we already are in space.The nearest habitable planets seem to be 4 light years away, no doubt we'll discover some even closer.Things like warp drives, black holes, anti gravity etc are theorised to get us there much faster than the 700k or whatever years it would take with current tech.Give it 60-300 years or so im sure we would be able to send an unmanned craft to a habitable planet, drop down a few adam and eves then fly away and keep them as a zoo we can visit while cloaked in invisible craft etc.One day in 200000 years when we are flying around in atom sized nano bots around humans at same stage as us now in the zoo, they suddenly invent nukes and we need to keep a closer eye on them because the tech can be so destructive.
Of the billions of likely intelligent civs out there already, many hundreds, thousands, millions etc years ahead of us, they likely made unmanned drones many many years ago that could travel and duplicate themselves, all while staying hidden unless they wanted to be seen.Parts or even the whole of the universe could be full of them, we just dont have the tech to see them.And imagine a 100iq human talking to an AI based race that has an iq of 1000000...
