The problem is that every "humanoid" in the game and in reality is designed near perfectly for advanced functions.
Then why do you eat and breathe trough the same hole!? this just means some percentage will choke to death. there is a whole slew of design flaws in evolved beings, due to the way evolution works. And that's before even addressing the fact that we can't interact with many "advanced" things such as radiation, or truly understand/imagine "advanced" things like time, distance and physics on scales just a few orders of magnitude larger or smaller then everyday life.
A humanoid shape is not the only form that can achieve a technological society.
More senses then the human ones have evolved on earth alone and much more often then just once. Eyesight has evolved like 7 different times independently of each other on earth, some animals can see more then 3 colors, bats use echolocation instead of light. Bugs use pheromones with their senses. Octopus are very dextrous while they don't have opposable thumbs. Cats have whiskers they use as a sense. Dogs can navigate by smell. There are plenty of examples of creatures that do not use sight as their primary sense but that function just fine, and there are also many specialized appendages to interact with things.
All these things are happening just on earth alone. How hard is it to imagine one of these other creatures evolved to become sapient instead of our ancestor? Sure if it was a mammal it would probably have ended up with a humanoid shape, but it might aswell have been a bird or water based creature.
Now imagine all of this happening with DNA that has 3 base pairs instead of 2.
Now imagine all of this happening with something that does the same as DNA but isn't DNA.
Now imagine all of this happening based on silicon or a even more exotic element instead of carbon.
Now imagine all of this happening on another planet, with different gravity, solar radiation, atmosphere, atmospheric pressure, season length, etc.
Is it really that hard to imagine something that doesn't have 2 arms 2 legs and a head that walks up right and grows its children inside a internal womb comes out of it?
there i replied now give me the cookies you promised.
