Do you think we are alone in the universe? Do aliens exist?

The universe is presumably infinite and has infinite matter. That is infinite chances for alien life. Gonna say yeah. However humanity may go extinct long before any visit Earth if they have yet to.

Statistically, the chance that we are the only planet with life is so miniscule its an impossibility.

but this galaxy, let alone the universe, is absolutely vast, and perhaps more importantly the spread of time is even larger.

And so the question is, are we the only intelligent species - are other sapient aliens out there?

the universe is about 14 billion years old, our planet about 4.5 billion. Life has existed for about 3.5 billion years. multicellular life has existed for 2.2 billion years. Vertibrates have existed for 0.5 billion years. the first land animal 420 million years ago. The first mammal was 250 million years ago and the first primate about 60 million years. the first tool using hominid was 4-3.3 million years ago - 1 / 1000th of the age of the first living creatures. Our species appeared about 400,000 years ago - 1/10th the age of the first tool using hominid.
we as a species built our first settlements and learnt to farm grain about 10,000 years ago.
We discovered how to make iron 2000 years ago, we made our first telescope 400 years ago. we built our first machine capable of flying 120 years ago, and our first space-capable machine 60 years ago.

But all the forecasts are we're going to fuck the planet enough to threaten a mass extinction within the next 100 years. our window for exploring the galaxy might be less than a few centuries before we die out, thanks to our own self-harm. we'll have walked this planet for not even 0.001% of the time life has existed. an alien world forming just 1% of the lifespan of the universe sooner or later might still have the equivalent of shrews, or have gone extinct while we were still hiding in holes from the dinosaurs.

we know of about 5000 stars with planets, in a radius of about 1000 lightyears. that's less than 1% of the volume of our galaxy. an alien species on the opposite side of the galaxy would never see us.

Statistically we are not alone - but realistically, we are truly alone in the cosmos.

Amazing and also a bit of a depressing response, thank you.

That's about what I thought. That we are probably the most advanced species right now, maybe within our galaxy, but I doubt we are truly alone in the universe.

Just that it would take many lifetimes, likely centuries, to even leave this galaxy. So aliens visiting us, unless they have more advanced spacecraft, probably wouldn't be much different. It takes so long to actually travel in space.

Then we think about how we've treated our own planet, and like you said, we could die out. That's.. really fucking sad honestly.

In a broad sense, we are all aliens to each other.

<---- see, someone put a hexagon on saturn.

our limits disallow constant acceleration at g's that would allow us to travel to the nearest stars in less than lifetimes; this may be true of alien life as well... the speed limit disallows 'visitors'.

Why not? Universe is unimaginably vast, gotta be aliens somewhere. Will we ever make contact is something, plus aliens don't even have to be as intelligent as us to exist.

That's actually a portal for where souls go. Saturn is not a planet.

if i were a hexagon, i would put a hexagon on saturn...
