It seems to me that most instances of first contact in fiction places humanity with our back against the wall fighting off a superior and hostile alien species (never mind that the other species is 99% of the time technologically superior). Perhaps this does make a better and more clear-cut story, but it disappoints me that very few stories have ever dealt with humanity coming across a lesser or peaceful race. Considering our nature and our past as a species I don't say it's beyond even our future selves to take over or attack a newfound planet. I'm sure works involving this premise exist, but I cannot think of many. Do you know of any good backwards-alien-invasion stories?
Also, don't say Avatar. Those people were Indians, not aliens.
