to add to this “humans are weird” thing
did you know that humans are the only species on earth with the ability to throw things with any significant degree of accuracy and force (apes can throw with about the force of a human ten year old, but cant lock their wrists well enough for accuracy)and we just never really think about it bc its so easy and simple to us that pretty much all of our sports are based around the concept of throwing things accurately
so
what if the concept of projectile weapons takes most species FOREVER to get the hang of, or even come up with in the first place.
a human goes onto a ship and throws some trash into the nearest reclaimer, shouts “kobe!” and all the other aliens on board absolutely LOSE THEIR MINDS
