Not until CGI aliens with non-humanoid body plans become cheaper than masks on human actors.

It's the relatability to the audience that mandates they have human faces. ... because humans can only interpret the facial expressions and emotions of other human faces. Star Trek was never meant to be Sci-fi so much as soap opera in space.

I think you may be mixing up the causation. How probable our universe is, we'll never know (until we can see other universes). We do know that in this universe, life exists. Thus our universe has to be "fine-tuned" for us to exist because we do. As for the universe "favor"ing life, that doesn't really make sense either. I think it's safe to say the universe favors stars, gas giants, black holes but it's pretty hard t…

I mean, you can calculate the probability of an abiogenesis event on pre-biotic Earth (or in our Universe in general), and then run the probability against the known number of solar systems/planets/atoms in the known universe. Whether or not the universe favored life can be interpreted from the resulting improbability and the current results. Stars, gas giants, and black holes are probable.

The assumptions probably dictate the probability more than anything else.

We don't even know how life originated on Earth

Farscape did pretty well with having relatable characters played by puppets.

NO. If solar wind caused a gas layer to evaporate, Earth shouldn't have the atmosphere it does. This planet should be like those surrounding it. Those same solar winds/radiation would have made sure of that. The issue I have with this is the same issue I have with evolution. If conditions were not created to favor life why are we the only planet with any known life & which is perfectly suited to a variety of life? Do…

... up until about 15 years ago we only knew of 9 planets so our sample size was pretty small

> because humans can only interpret the facial expressions and emotions of other human faces.

Arrival was pretty good in showing actually alien aliens (while falling into the trope of godlike aliens).

Watch some octopus videos. You may get a sense of a certain connection, empathy, between sentients that transcends our physical forms.

Star Trek was ever meant to be Sci-fi (search how Roddenberry and Asimov became friend). Soap opera in space is what CBS want it to become because it is so mush easier to write for (see Kurtzman-verse).

> This could be a boon to scifi plots But can they outgrow the trope of every alien being a human-in-a-mask?

Aren't we already there?

It's a coincidence that a carbon lifeform like you is standing on a planet perfectly suited for carbon life, wondering at the chances of happening to be on the right kind of planet?

I don't remember that scene from Hitchhiker's Guide, but it must be in there somewhere. The collolarry to the whale wondering why it is hurtling down towards the surface of a planet..

Isn't this the distinction between the Strong Anthropic Principle and the Weak Anthropic Principle? WAP: we're going to see selection bias in our universe because the preconditions for life must have been satisfied for us to exist within it. SAP: all universes must satisfy the preconditions for life because cogito ergo sum -- the definition of existence requires life to perceive it. I've probably sold SAP short becau…

Rather than cogito ergo sum, I think esse est percipi is the more appropriate phrase to use here.
