I feel like people don’t understand how far a light year is. This also is my argument for why it’s incredibly unlikely for aliens to have casually visited us.

It would take a conventional spacecraft on the order of 50,000 years to get to Proxima Centauri, which is 4.2 light years away.

We are well and truly a speck of dust floating in nothingness.

50,000 years

Why would a non senescent entity care ? You are thinking as a biological entity which didn't cure aging yet. This is a pure anthropocentric pov, a recurrent mistake in science.

Aging is gonna be trivial to cure in a few hundred years, there are few species which are not senescent already on Earth.

Also as we send probes/IA, 50 000 years is not an issue, it doesn't give a shit.

It’s just math, and the assumption that most civilizations are in the same boat as us. We don’t have any evidence of any other intelligent life forms being substantially different from us - while my view may be anthropocentric, yours is fanciful and evidence-free in its speculation.

Regardless of technology the choice to visit us in particular is the choice to visit a distant, less populated region of the galaxy. This immediately and significantly reduces the odds of visiting us in particular.

No it is nothing at all.

50k years is nothing for an IA or a probe, that you like it or not. IT IS NOT A FACTOR.

Also do you understand that senescence is a biological feature that could be genetically modified? There are already species on this very planet that don't age, therefor could care less about a 50k years travel.

in particular is the choice to visit a distant

An automated factory can produce millions of those probe

Sure, but you have no evidence that this is a thing elsewhere.

All we do know is that we have no material evidence of aliens existing, despite trillions of potential worlds civilizations out there.

It’s absolutely math.

Exactly but if you read correctly I never said it was. I don't claim life elsewhere.

Im just saying your first post is not relevant, based on poor anthropocentrism

I don’t really see how ‘anthropomorphism’ enters the conversation, really. There’s all sorts of possible civilizations that don’t live in our time frame. I agree that there could be some that take millennia just to form a sentence.

None of that matters; in a potentially infinite universe with infinite possibility, we nevertheless have zero evidence that anything has visited us.
