We are human, we have done almost this exact thing for thousands of years and leave ecosystem devastation in our wake.
People with rockets would absolutely go down to that planet without a second thought.

Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

Yep i would expect them to send the blankets down from orbit first.
intergalactic tour guide: now if you look to your left, you’ll see the natural habitats of the Xpheno217 species. This is the only location in the whole universe they can live. And to your right, a brand new residential community fit with Walmart and their very own Chick-fil-A.
I'm sorry. I can't let you do that.

That won't stop humanity. I've seen enough movies to know that a man-eating crazy alien monster infestation isn't enough to keep people off some rock they found.
And they'll bring that shit home too.
On the other hand, the two biologies could be so different from each other that they don't interact at all.
This is an interesting idea. If neither biologies used the same fuel molecules then they wouldn't compete for resources, but perhaps they would compete for space? But then if both biologies were that different from each other would they be able to even live in the same environment?
The sci-fi book Children of Ruin (sequel to Children of Time) covers this somewhat. There humans encounter a planet with a breathable atmosphere but with a toxic environment that slowly kills them.

But how else am I supposed to get green *Orion trader women on my arm?
If the biology is different enough, things like viruses wouldn't easily cross between the planets. But bacteria could still probably exploit us (and them), and nothing would stop things with claws, teeth, and spikes from hurting us even if they couldn't ultimately digest us.
Ah, drat! My one weakness! Claws! Oh, and teeth. So two weaknesses.
Oh, and spikes.
Oh, and fire.
Pointed rocks.
Long falls off of cliffs.
Ok, I have many weaknesses!

I heard on the radio that bacteria is what killed the Martians
Even if the alien species had completely incompatible biology (no DNA or RNA), a human body is still a warm habitat that contains water and useful minerals. So something small would probably settle inside of us.
And our immune system couldn't interact with it and therefore not kill it.
There's an entire very large genre of scifi about this very topic
My brother, we have spacesuits and decontamination protocols.
Also, by the time we get to meeting other life forms on other planets we'll have cracked genetic engineering enough to make that inconsequential.

We won’t even be able to reach it until we can figure out FTL travel or technology that can support multi-generational passenger ships to get there.
FTL travel implies a mastery over spacetime itself. After that, a practical time machine is a matter of engineering details.
We can be sure that we never get there because we are not flooded with tourists from the future. QED.
For that matter they have not sent travelers to us.
As a kid, I once heard the theory that aliens are actually time travelers fucking with people.
i wouldnt call it mastery, implies you can control spacetime as well, just finding ways around the speed of light limitations.
at least beings shows that control are close to being godlike energy beings.
I love the hubris of this argument. It's the identical construction of guys who say a woman must be a lesbian if they reject thier advances.
That depends on the type of FTL we use. Some just require infinite energy or exotic particles to work. No mastery of spacetime needed.
You don't need FTL travel or multi-generational ships really. If you get close enough to the speed of light, time dilation can make the travel time for the people on the ship be as short as you want. Only for the people that stay on earth would the spaceship appear to take generations. Getting enough energy to reach such high speeds would be the difficult part as well as accelerating quickly without crushing the travellers.
And presumably not vapourising from collisions with random particles in space while travelling at a significant fractions of C.
Reminds me of Deathworlders. Some woman got stuck on a planet and had to take a shit and the microorganisms in her shit wrecked the planet.
Oh no, a HFY story... They are kinda entertaining but filled with so much weird pathos and self-dirision. That "btw, religions suck" section was just so out of place.
Imagine that: Getting abducted by aliens, fighting and winning against some of the most dangerous aliens of the whole universe and when being interviewed about it, one of the first things he chooses to say about humanity is "btw, we have religion and it sucks".
And these stories go on for all eternity. 97 long chapters.
That's what you get when people on the level of fanfiction writers write original stories without any oversight by an editor.

What does that life taste like? Someone will figure out how to prepare a dish that is truly out of this world.
Shouldn’t and couldn’t are too different questions.
Sexy results?
There's only one way to be sure: nuke it from orbit.
They're talking about sex 😉
Well we can't have infinite growth without infinite exploitation ConstantPain. Duh
We send a member of MAGA to explore first, then dissect them and evaluate the results on the body before exposing the general populace to the atmosphere.
Why would your first act on alien life be to launch our vilest weapons of mass destruction?

Sure we can. Just send a few people to test the waters first.
And risk wiping the life on that planet? Considering something like that happened to native population in America, I guess people don't care.
That's why this is done: https://www.nasa.gov/ames/space-biosciences/planetary-protection/
I realize you were probably talking about visiting other worlds in person, but we would probably still have unmanned missions there first.

Isn't it also possible that their biology would be different enough that there would be basically no interaction ? 🤷🏻♀
I don't think we have any micro-organisms that would be particularly dangerous to silicon-based life, for example, if we did I'd expect it would be a problem already for our computers and everything made of glass ?
No we will, the bigger question is if one of the parties will have sex or dinner.
