With all due respect to your arguments, you are missing the point: A handful of bacteria can kill you -- does that make them more intelligent than you are? Can a lion drive a car? Can lions design and then build a car?
Complex tool-using is a higher level of function. A chimp can poke a stick into a nest of ants, but that's a pretty simple tool A crow can drop a nut onto a rock from a height. Neither of these actions put them into the league of people who can write on computers created by their kind, using language developed by their kind, discussing abstract philosophy developed by their kind.
Bring me the xenomorph who dreamed up and then built the alien version of the Mac, that'll impress me.
Can't find him? What a surprise.
Intelligence doesn't mean you as an individual can't be stupid, ignorant, or arrogant; it doesn't mean you can't make bad choices. Stick your hand into a rattlesnake's cage and stir the critter up, that's pretty stupid, but there are plenty of humans who have better sense. One idiot doesn't define the species.
Intelligence is a survival characteristic -- if you are circulating acid for blood, have big teeth and tough skin, you don't need to be particularly intelligent to survive. If your queen lays thousands of eggs, you are expendable, and intelligence is a waste.
If, on the other hand, you are furless, have mostly-dull teeth, fragile skin, you can't run fast and aren't strong, relatively-speaking, being smarter than the critters who can outfight and outrun you is a way to stay alive.
Xenomorphs are war toys, developed by some species a whole lot smarter for biological warfare. Nothing else makes any sense. If they evolved naturally, they wouldn't be at the top of their world's food chain, otherwise, why acid for blood? Like the South American frog used for arrow poison, the reason you have acid for blood is to make you taste bad enough to keep something from killing and eating you. Think about it.
You might not like how Dark Horse has developed this universe but they did develop it, and their versions makes a lot more sense than the movie versions.
Humans, as a species, have better reasoning abilities than xenomorphs. Period. Full stop. End of story.
If you can't see that, that's fine. Not my problem. I've tried to tell you, you just don't want to hear it.
What the heck ...
