There where hundreds of movies and tv-series showing extraterrestials from distant worlds. Giving how life on our planet evolved and considering basic components necessary for intelligent life to emerge, who in your oppinion might have been the closest in depicting alien visitors from outer space?

There’s really no way to know until we start finding other life. We know the components and evolution of life on Earth but there could be other ways life can be created. Astrobiologists have done a lot of work in this field trying to determine what the possibilities are but without data we’re pretty much blind.
The common feature of most TV shows and movies is that intelligent alien life is somewhat humanoid. That makes sense for anything made before computer generated graphics (CGI) since actors are (mostly) human. With CGI anything is possible now but who knows?

I consider myself a science fiction aficionado as well as a (takes a deep breath) UFO buff. It is safe to say, therefore, that I have seen my share of what extraterrestrials “should look like”, according to Hollywood and so-called UFO witnesses. Unfortunately, most, if not all, of these so-called “aliens” are a direct results of anthropomorphic biases – bestowed upon us by the greatest of all special effects artists on one side and alleged UFO encounters on the other. In a nutshell, the biases have directly shaped what extraterrestrials, from a human perspective, should look like. Most, if not all, of these aliens appear to look strikingly similar to us: a head, two eyes, nose, mouth, two arms, two legs, and in some astonishing situations, they even speak … English. Nonetheless, If I were to chose my favorite “alien”, I would focus on the latest movie The Arrival. These extraterrestrials, which are heptapods, sparked my interested in contemplating what type of planet these aliens could have evolved on. Because they were large and could not breath oxygen, we can speculate that gravity and a unique atmosphere directly influenced these aliens. Nevertheless, The Arrival is science fiction and any portrayal of extraterrestrials, from humans, will unquestionably be wrong.

I think it’s safe to say that none of us have any CLUE what life might look like… just talk to a biologist to get a sense of the complexity and seeming randomness of life on Earth and its evolutionary pathways.
That said, I loooves me some science fiction and fun speculation. Of course, scifi for tv and film is often limited. In order to tell compelling stories over long periods of time with complex characters, you often need human actors. Thus, we get the “humanoids with bumpy foreheads” in so much of our television and movies. Even with CGI available to us, storytellers will create humanoid forms because that is what we tend to identify with emotionally.
I like to sneak off to books to find truly bizarre descriptions of potential alien sentients. My favorite is the Galactic Football League series by Scott Sigler. Though his universe teems with intelligent creatures with all kinds of bizarre (though, admittedly, often Earth-like) forms, and their physiology determines what positions they play in American football. I can’t think of a better way to get a sports fanatic excited about science fiction! It also makes for some bizarre cosplay options when we go to conventions… Anyway, with full color illustrations in some of the books in the series, you can really enjoy the possibilities for sentient species there.

Probably one of the most realistic is ‘Contact’ with Jody Foster based on Carl Sagan’s book of the same name. In a nod to Fermi’s Paradox, the Vegans (people of Vega, not non-meat eaters) developed technology first and are thus far more advanced than we are. They don’t so much visit Earth as give us a technological boost to help us transcend our basic corporeal bipedal primate existence.
Paul Carr (Space Systems engineer at NASA, podcaster, blogger, investigator)
To me, science fiction movies and TV shows are not so much about aliens, but about ourselves – human myths, nightmares, hopes, and aspirations. For example, Klaatu in The Day the Earth Stood Still is not alien at all – he is an idealized human, and in fact brings the Christ story into the atomic age. ET seemed to follow a similar pattern, but he wasn’t as preachy. Most of the Star Trek aliens are really just exaggerations of human traits that we either fear, admire or detest, and Q is not unlike the all-powerful, omniscient, severely judging God of our Abrahamic religions. I have to admit a mild fascination with the Vulcans. What would it be like to always act rationally?I don’t know the answer to that question, but I don’t think Vulcans are really all that alien.
Aliens that were really alien would be too hard to understand and would not serve a good role in an entertaining narrative. They would, I expect, be about as far from Dr. Who or Chewbacca as I am from a three-toed sloth. I am not talking about how the aliens look, or how many eyes they have, or whether they swim in a vat of blue liquid – details I regard as relatively unimportant. What you won’t see on the surface is how they evolved, which governs to a great extent how they approach and perceive reality and how they think. If, as would be necessary for visitors from other worlds, they are the creators (or at least the heirs) of unimaginably advanced technology, then they think with great power and solve problems we don’t even know exist. We don’t even understand yet just how alien this would make them, or how absurd and puzzling their motives and actions would be to us. We certainly don’t know why there would be here, but it is unlikely to kill us, to eat us, or save us from ourselves.
Such aliens as I imagine, if they exist, would make lousy movie villains or heroes, but I wish someone would try it.

Although we envision aliens mostly looking like us, there is no reason to not think that some yet to be discovered chemical and organic mechanisms, might exist elsewhere in the Universe that allowed for the rise on other worlds for the formation and rise of species that do not even remotely resemble us.
Just by looking at the shear diversity of Carbon based life forms right here on Earth, gives room to imagine the existence of many other varied types of non-anthropomorphic looking alien being. It is hard to pinpoint one fictional representation of an alien species by one of the many Science fiction artworks. But if one popular franchise comes to mind, that would be Star Trek. In their long running shows, the creator of this, one of the most successful sci-fi/space franchises have been able to present a tremendous diversity of alien species to the audience, thus sparking the light of imagination in the human mind.
