grey alien =/= humanoid
I am talking about grey aliens specifically. The concept of an alien which ends up looking more like us than other primates do. Also, since the trait I am revolving around is intelligence - I am only talking about species which are intelligent enough to develop civilization. We are likely not the only humanoids in the entire universe, but I find it much more likely that intelligent life would take on one of the other myriad possible forms life can take than for it to just look almost the same as a human. As an example, two other species commonly known for being highly intelligent are Corvids and Elephants. If even on earth there are very smart species that look totally unlike humans I think it much much more likely that whatever intelligent life we find out there will look different to humans.
Humanoid traits are not one big package, you can have a number of human traits and not be a civilization. Nothing other humans have requires advanced intellect. Heck until 70000 years ago we lacked the genes needed to be a proper civ building species despite looking anatomically exactly like modern humans (anatomically modern humans evolved 200000 years ago, behavioural modern humans arrive 70000, the development of advanced and more modern cultural behaviour was 40000).

From an evolutionary standpoint does the grey alien make sense? I know many depictions make the head way too large for the body to support.
