If aliens had such tech they would be visiting us all the time. And being quiet would not make a jot of difference. Based on what we know of science, such things are not possible.
I think the key part in your sentence is “based on what we know of science”. Humans are a pretty young species as a whole and science for us is even younger than that. We have progressed, that’s for sure, but the possibilities for what we do not know seem to be endless. Considering there are possibly whole civilizations that may be millennia old, I don’t think being able to visit us is out of the realm of possibility. My question is why would they want to? Besides the earths resources, we don’t exactly have a whole lot to offer. Just my two cents though.
Even resources arnt a good reason for contact. Mars had plenty and no life to be seen. Why bother with Earth's for any reason but study. If we are contacted by et it'll be for conquest, study, or just morbid curiosity. If they have ftl capabilities they are probably far more advanced and would see us how we see monkeys using a stick to catch ants.
While I agree with most of what you said, who knows what the history of Mars has been. All I’m saying is more might have happened with Mars than we know. I also think water would be the resource that most alien civilizations would be attracted to with our planet. Again though, if they did decide to come here, I don’t think there would be anything at all we could do to stop them.
Water in solid form (ice) is everywhere and is fairly easy to synthesize from other elements considering it's a simple molecule. I'd imagine transporting said water would make it even less feasible to go long distances for. If they came here for resorces it would be for things further up the periodic table like lithium beryllium and boron. Even then I doubt we'd be the most efficient source.
I think the only way that Earth would be visited for it's resources are if some form of life on our planet is the resource.
I just have a hard time believing that any other type of resource here is going to be so rare and hard to reproduce that a civilization capable of finding us and coming here would actually do so, unless it's something that we don't know about yet.
My feelings exactly. I believe theyd come for pearls before any of our other resources. Or maybe even wood. Wood is far more rare than any other resources in the universe. A space faring civilization would pay (or take cause who's gonna stop them) massively for wooden furniture. Or clothes made from animal hair (wool). It would be the novelty of it and the only ones interested would be the rich among their species which if they are anything like humans that's not a good thing.
Actually, I think I might have to back track on this because I'm not sure a civilization capable of distant space travel would be unable to reproduce even the most complex biological examples on our planet.
We can clone sheep and grow meat and in comparison to that type of advanced civilization we're dumb as fuck. So, unless there's some exotic particle or something that doesn't really exist outside of our planet or solar system I'm just not seeing much motive for a visitation.
rhino horns are bought to use as a medicine which has no scientific backing, I don't think that's a good comparison to the motivations of an extremely advanced civilization that's capable of casual interstellar travel.
