If a planet had enough of an air supply to allow a deep resonance of species in livable conditions, to escape that planet the whole species would need to harvest something that by any greater need would allow the species to also endanger itself well enough to need to escape to that space.
When the space is no longer faring in its base-for-itself form, we are carbon, that base of life will render to what the most occupied spaces are used for and the outlying and living in dangerous conditions of formidable space routine beings there would need to extract from something a new version of some greater or lesser form of the same thing, for secondary purposes and for not saturating the exact species to anything a purer breed of being might rely on for separating existing lifeforms with past ones.
If the past ones were to navigate to space and require the existing forms' current environment to harvest, which is what it sounds like (Aliens Resurrection) the living condition would require a living form of the existing past form, but not the requirements for it to meet any kind of doom. That might be a sort of rapid expansion idea that does not linger in outlying dangerous conditions as they exist in space the way we know them to (long distance, long time).
When these conditions don't meet to exact real or alternate forms of what might be bridging the current need to what these beings might need for us to extract what is at the deepest of it, the aliens in the situation could offer their "young" to rival the current state of what they are doing to have the existing species offer itself as a living form of that extraction to allow itself to gain that outer peace.
So we might be able to alienate what offers women in this life to men, their ability to feed an entire family, as like what these species might do to the extraction process as it turns the civilization of prowess, to enlarge a colony is to offer it more resources, the shortest hand of that ability to extract would be to make them a powerful workforce that then relies on the same power of extraction as the powerful and principled issue of what an extraction process might create for something secretly looking to destroy it, so that the existing colony, and not the space faring colony, to be able to actually navigate a modern form of the same thing without extracting its own youth to offering it. That when that youth is offered they create intelligible programs that design a method to remove that youth, the space faring colony need only devise what the instructions of that living and in fact civilized colony may create to extract what the space faring colony may need. Even if only as the surmount of fuel to lead it to a new colony and leave enough behind to grant itself another extraction point.
The extraction could be, by our standards, water. It otherwise could be blood. It could be the remnants of bone and or the existing tissue as it regenerates over the processes that continue to understand our bodies well enough to protect them as in the fingernails. So when that process isn't busy enough to make the richest of the soul what is busy to making the not so rich parts a not good zone, the richness in the soul is what grants us a colony that can handle the task of excavation. That gives it colony for proof and manages that in distinct parts, the colony can barely understand itself well enough to cater to the whims of any underlying youth as the process of development, essentially enslaving them, but then also originating that fact within another origin in case the understanding comes from the greatness of what richness is in the preposterous outcome of the underlying youth, which would be slavery if the work were not intended to offer them the greater of the richness as of those in inheritance. So to speak.
The generation here is not in name but in trade and that would by extraction also offer what the blood in the bones can't generate to the occupying lands so that the existing pair of parent and child cannot originate the pair without the help of the existing movement of process into space (so no one actually brings their children with them but that isn't some sort of offer for peace, it's their actual way of life). That would make it dangerous to speak on the generation of youth for it would be foreboding but also offers work when the young one cannot contemplate the absence of work, as that is not the colony of the worthy extract.
It is just a bold reliance on the same exact nutrients, to gather nutrients these are the strongest parts of the body, the literal element of that disguise, none of the space faring would ever require themselves to destroy what is in existence in the zone of their planets, then, the exact anatomy of that physics would only be required to someone that is in the original colony by the space faring and the existing points for that extract, like Tatooine, would be the colony for its own entertainment, and not for the busy parts of its plot to originate that it has an entertainment for the body of power that the space faring have in their most valid insights.
The creator of this situation would be within origin and their most valued trait, possibly intelligence, would be the exacted and minimal exact point of the conversion to between planets and for to be used in their attempt to mind a non-criminal escape. As they astound themselves to find that they have indeed extracted only the most common points of insight to actually gather the same points as prior to finding that perhaps the formula may be pointing at them. And this way, the traps in leasing to that land a fortune of its own youth, that extraction is not in principle and the only regained part of that exchange is the conversion process and that would be to alienate what of the space faring colony was not able to ascertain in the conjunction between what is here and what might be the dividing factor, a youth of work and a youth of rebellion, to existing between what is in work and what is, in fact, simply a way of life that does not escape into space.
So that no-one sacrifices anything and the destroyed and simply, and only, in remnant, a disguise of what warfare might reveal to those of any space faring, minding, and workful exercise of what the criminal mind to create a genocide might create in the possible extraction of fact to the extraction of faith in the use of regular expansion and not rapid, to allow that the extraction be a deep and rich one WHILE the removal process is kept in place to create a free workforce, that will in turn also allow the exercise of food and fuel to remain the only piloting factor to allow extraction as possibility. Like in Gurren Laagan. Except only for minding their men as opposed to their women as they have it in Gurren Laagan.
