Again, how is this really different from any other colonization project? Look at the history of colonization in the Americas, and you'll see that many died out entirely as a result of being unprepared for the environment that they encountered. I suspect that you'll see similar results in the history of colonization into Australia, and if records existed, for pretty much any migration into areas where humans had not been before.
Can anyone in 2014, with a straight face, write that the Americas and Australia were places where "humans had not been before"?
Such statements don't withstand the scrutiny of someone with even gradeschool historical knowledge, yet here we are having to chew on a +4 comment that forgot humans were in these places well before Europeans got it into their minds to begin displacing indigenous peoples.
Imagine a colonization trip to Mars that discovered humans who had been living on Mars since before recorded history. These indigenous "Martian" humans then sheltered and fed those of us who traveled from Earth, receiving as thanks a colonist-driven campaign to kill them and appropriate their resources AND THEN two to three hundred years later the colonizers "recalled" how exceptionally difficult it was to colonize Mars, a place where no humans had been before.
While the likelihood of finding indigenous humans on other planets is unlikely, one day our descendants may encounter extraterrestrial indigenous life forms and, with thinking like the kind exhibited in your post, would destroy those life forms, appropriate the liberated resources, and write a history that enshrined themselves as resourceful adventurers struggling to survive in a harsh "unlivable" environment.
