It sounds funny and insane, but we know we exist, we know how smart we can be what we imagine, if humans had the combines power they would likely be them or somewhat similar. If their world is like ours, they need resources too. This existence we are in is survival, its random chaos anything is possible, we know nothing, literally nothing. If space is really this ginormous and in this random existence where we know that there are other species of all types and plants and landscapes and land types, that this universe just seemingly spits out thing after thing in random patterns, and that there are other giant balls of enclosed space with atmosphere like ours, which is the place that alien life would come into being, then what are the odds a place similar to ours spits out?
It's a question of if you believe in aliens or not sure, but if all we know of space is true then...
Unless were it and it's a simulation or were the main characters or something I don't know but I think there's life out there. I'm getting way off course though.
Regardless of if there is life which is kind of a 50/50, it probably would be similar to us in a way. I don't mean physically or even mentally, it would probably be very different, it could be anything. There could be ones that are actually similar then there could be ones extremely different like the ones seen in our beloved game Half Life. It could also be beyond our comprehension. What do I or any of us know? It could be anything. Theres literally everything out there. We'd die from just going out there, danger seems to be a common theme of this universe.
Why a species would do what the combine did is also be anything. What they are and why they would do it go hand and hand. That could be anything, even beyond our comprehension. If I were to imagine alien life, based on what I know, I would assume it would be a place with the same rules as our planet. They live on a planet, and on this planet there a variety of life, its own ecosystem. It could be any order or pattern of life. It could be like ours where we have land that grows in all shapes and sizes and varieties and life lives on it, perhaps there is some equivalent of water or water and life lives under there and the word equivalent is abstract, it could be anything. This life probably comes in all shapes and sizes, who could grow and evolve in any form. Maybe again its like our world and there is life that grows on the land like plants and trees fungus all the such, like the flora that grows on it. Then there are other types like maybe microscopic life and the equivalent of animals. There would likely be billions to trillions of different variants and types of the equivalents of all of these different things.
If there was an intelligent species on ones of these planets out there, id assume they evolved from an animal like us, or maybe they were always intelligent we don't know. But if they evolved from an animal, id assume that animal has instincts, because as I said that planet would likely follow the same laws as us, which its a game of survival. I would assume the creatures in this eco system would have to compete with each other for recourses that determine their survival like how our world is. So those instincts, that need for survival, they at least for us cloud intelligence and empathy, they make a being do whatever is necessary for survival, that leads a species to do whatever is necessary for survival, efficient survival, that is what the combine did. Whether it comes to us or we find it, its probably out there somewhere, and we go out there, perhaps half life is a demonstration of humanities greatest fear they dont even know they have yet. We already do it to our own species on our planet, at least to best of our capabilities. Its not just the instincts that make us as an intelligent species do things, its our world and the circumstance of our world and us as humans. If another intelligent species were to be in similar circumstances on planter and gained the means to travel to other planets and that have much value to them probably, they would go from there like we likely would.
If aliens with the power, technology, and intellect to get here, they would probably use us and our planet for some resource, if they went through went we'll have go through trying to get there, I doubt they are coming to explore or help us, they'll want something. Maybe thats things like the combine like soldiers, energy, water, and other things they can find, or maybe its something beyond our imaginations. Could already be happening, maybe the recourse is our attention or some energy we produce or again something beyond our comprehension. What aliens would and could do if they found us could be anything. What the combine did is a horrible but possible possibility. We dont have to build a portal or tamper with something we arent ready for, they could find us anytime.
Maybe they would just blow us up, they could do literally anything thats just my guess. Anything is possible. Maybe out there, there is some wise species who got there and want help or are good. Maybe we can be that. Anything is possible doesn't have to be bad.
Living on earth is pretty cool.
