There are no resources on Earth that a space fairing civilization or robot would need that they couldn't get far more practically from asteroids. Earth is a gravity well, extracting resources from the planet and getting it off is way harder than just mining Kuiper belt, lots of water, minerals, metals anything they would need.
- bluGill 5y agoOne exception to that: gravity. The only reason I can think of they would want our gravity is if they want to live here though, so we are back to them not sending robots which we already agreed isn't likely.
- candiodari 5y agonot just gravity. Really a whole host of environments that at least we ourselves find very helpful in a long list of production processes.
- baja_blast 5y agoThat's a good point, Earth would be a nice place to live if their home planet had comparable gravity. But conversely, Earth could also be very uncomfortable for them for a multitude of reasons. Like imagine if we discovered a planet full of life, but it had a dense very wet atmosphere that to us would be unbearable, but to the native species perfect. Also imagine if humans do go out and colonize new planets, these people would go through rapid changes morphing into another subspecies each adapted to conditions of the planet they moved to.
