It's happened before, over and over again. Remember? When you read the Brooking's Institution report?
You mean from creatures that do not have the ability to navigate dimensions or travel faster than light? Because that does make a rather enormous difference.
Don't be kink-shaming the aliens.
Also, if YouTube has taught me anything it's that people who post the most inane things get millions and millions of views. Who knew there was an entire genre of YouTube videos that focused on people just eating? I think there's one that's pretty popular that's just a girl eating different kinds of bread.
Don't think I didn't consider sex as a possible motivator. There are some fantastic books that include that, unfortunately I'd give away spoilers if I said the name but... it's a consideration. In that book though, it was we who discovered FTL travel and were interesting from a sexual perspective to a less developed species. Makes a big difference.
I would imagine that an advanced biology would also be advanced from the perspective of sex, either in bypassing it completely, or in tailoring biology to it specifically (I suppose it's possible that they never needed it in the first place, but that seems unlikely based on what we know about gene propagation, which is the underpinning of life as we know it). We humans would have as much to offer as, say, an apple pie. Ok I'll stop here.
Maybe not cultivate. Its possible they just like their recipe books and the racial Porpoise jokes, I mean they maybe an advanced civilisation but still racist a-hats and bad cooks.
I still don't think they'd be eating, at least not the way you or I think of it.
That doesn't matter. Everything concerning aliens is not credible and merely speculation. That doesn't mean that people (me, scientists, everyone) can't speculate about aliens if they are hostile or friendly.
Well I think some people try to put forth credible theories, like
@Dotini's Brookings Institution Report. But theories based on what humans have done (which is our big example of technologically advanced societies interacting with less tech savvy groups) don't particularly apply to a species which has advanced to the point of interstellar travel. That might have been less apparent in the 60s than it is today, as science continues to develop in so many areas much faster than FTL dvelopment.
Please read the Brookings Institution report, kikie. Then you'll know that entire civilizations have declined and perished upon encountering advanced foreigners with their armor, weapons and technologies. Often, their economy and belief/social control systems are upended.
See my response to kikie right above this.
That sounds like the kind of thing people would watch. Maybe not everyone, but a certain subset. Although the aliens wouldn't be human people (unless they are for some reason, like maybe the Earth is the planetary version of South Sentinel Island originally colonized by a tiny group of anti-technology cultists, though they'd have to have messed with genetics to make us blend in) so maybe they would have a completely different idea of what is interesting or not.
Even if it were true, and we lack any and all evidence to support this, we also lack an understanding of how this goes south for us without grafting a great deal of low-tech human thinking.
I do agree that if they are sufficiently advanced they would probably have little need for Earth. Maybe they would stop by to collect some DNA just to have for a rainy day, but after that they might not care what happens to the planet. However we could ask what is the lowest level of technology a civilization needs to explore space? Is crossing the galaxy easier than building a Jupiter brain to simulate it on? Personally I find it kind of hard to imagine what human technology will look like after maybe 200 years. I don't what technology will experience the most growth over that time and what might run into brick walls. Then you also have the chance of significant disasters to disrupt civilization in such a way that we lose some technology but not others.
It does look like some basic understanding of certain physical phenomena is required to possibly achieve FTL or inter-dimensional travel. Especially an understanding of quantum physics and spacetime, which, I don't see any way around this, requires an understanding of computing that lends itself to huge developments in other areas. I find it somewhat non-credible to suggest that a species could achieve FTL or interdimensional travel without first altering their own biological makeup, for example.
