Why Haven't Aliens Contacted Us Yet? (Fermi Paradox)

[AgProv]

I heard the theory that silicon forms 4 bonds like carbon.

Why did life go with carbon instead of silicon ?

We could be transparent beings with silicon.

Then in the original 1951 movie “ The Thing “ the scientists were doing battle with an alien who was vegetable which was described as a dangerous carrot.

Supposedly, Warner von Braun decided the crashed Roswell UFO as a vegetable that was alive and its occupants would mentally become one with the UFO as the UFO lacked mechanical dials.

But my opinion is that planet earth having all the parameters is very rare.

But if you not afraid to go down the “ rabbit hole “ there are other dimensions and there are more than one universe.

Maybe it did. Look at all the folk-legends about trolls.

Also, Terry Pratchett's "Discworld" sets out a nicely-argued rationale for trolls as a silicon-based lifeform: it's just that as silicon sets out its own list of limiting factors compared to carbon, there'd be less of them, they'd grow more slowly, reproduce more infrequently and find themselves gradually crowded out by faster-moving carbon-based life.

Purple bacteria could be key to finding extraterrestrial life on exoplanets​

On many exoplanets, the best clue that life is present may be a purple hue. New research into some of Earth's most extreme bacteria explains why.

I never trusted borscht as a foodstuff.... this might explain why....

I think they are just letting all calls from this area code go right to voice mail.

I think we've actually had an answer to all of our transmissions. It translates as "Your call is important to us here at the Galactic Federation but all of our operatives are busy at the moment. Please hold. Your queue position is 1,110,004."

The background hum that we think is the remnant of the Big Bang is actually interstellar lift music.

And the call center is probably like this.

It seems to me abundantly clear, that if 'intelligent life' as we understand it has arrived on other planets in the universe, being it based on any thread of evolution from insects to crustaceans, when it reaches the point of developing technology it can no longer control, it destroys itself.

Since this trajectory on the evidence available to us only seems to take say 2500 years, there is no chance it will be in that tick of the clock sad technocracy will live long enough to get off their home system and make itself known to us. . It would not even be able to get out of its home solar system with physics as we currently understand it.

We ourselves have turned inwards and will probably never again go as far as the moon.

Ozymandias was more true than Shelley knew.

This is why Stephen Hawking and Elon Musk have said we need to get off this rock, to ensure the continued survival of the species.
If humans die and all we leave behind is AI, then that may be what aliens finally encounter.
I have this idea that what we call UFOs and aliens may in fact be AI-driven machines, left over as a last remnant from a long-dead alien civilisation.

Well, I'm sure their glowing eyes won't suddenly change from blue to red when we ask them what happened to their biological predecessors...
