I dunno I think if it were an alien spacecraft we should just keep our heads low and not draw any attention to it. Our first window of opportunity might be our last.
I've gotta disagree with you on this. Personally I think intelligent life is probably very rare in the universe, the sheer number of factors that need to go right for it to arise, and then the sheer number of factors that need to not go wrong for it to continue to exist mean any intelligent life out there is probably going to find us way more valuable and worthy of co-operation and interaction than say destruction of…
As a counterpoint, I'd argue that conflict can act as a "force multiplier" of sorts.
Every large war in our history has caused leaps in technology. Even on a smaller scale we treat conflict and competition as a good thing that promotes innovation.
Life as we know it "craves" and thrives on conflict. And if that's a universal truth, then any other civilizations we meet could as well.

#54There's only one apostrophe in the name. It's not quote marks. https://en.wikipedia.org/wiki/ʻOumuamua Or to be really specific https://www.fileformat.info/info/unicode/char/02bb/index.htm "typographical alternate for U+02BD or U+02BF used in Hawai`ian orthography as `okina (glottal stop)"

What if intelligent life is rare because at some point some other intelligent life set up a systematic process of keeping the universe clear of it?
Then we'd certainly have evidence of this genocidal society no? They'd definitely be actively looking for other intelligent life forms, and if they were systematic in eliminating it, they'd have to have the infrastructure to do so which we'd be able to detect. After all you catch more flies with honey than vinegar, any life form like that would have the interest in finding and eliminating intelligent life before it b…
Maybe the only cosmic infrastructure required would be listening stations and the ability to steer big rocks to sources? The listening stations would be hard to pick out. They could run a 'reverse' fermi equation of sorts and figure out how fast you need to detect and extinguish signals to keep the universe clear. Would the extermination look anything more than unfortunate random collisions? Do we actually have enough data to calculate if collisions are above some noise floor of random happenstances?

On the flip side, the conditions required for life to reach interstellar technology are so rare that life-bearing worlds like Earth are highly coveted. A planet where you can set up a city and not have to worry about micrometeoroids, radiation, atmospheric composition? Just sleep out under the stars without a suit repair kit handy? That’s worth killing for!
If you can make the trip you can probably survive in space definitely. I'd be surprised if truly space faring civilizations really like gravity wells. Getting up and down them isn't cheap (although with plenty of effort it can be made cheaper). Everything is all stuck together, if you can find an asteroid of the material you want mining it and moving it for sale/manufacturing should be so much cheaper than dealing with moving a bunch of unrelated materials away under gravity.
In space you'd be able to move arbitrarily large objects with just an accelerator, map of the solar system and a transponder. In a gravity well you need a lot more and way more $$$ if you want to get it up the well.
Then again I have no training in the subject.
