I want to see your opinions on the "Rare Earth" hypothesis

Basically it's a hypothesis that argues that the circumstances in which humans became sentient are too improbable to happen again in our finite universe.

AKA Theoretically, we're the only sentient race that ever existed forever.

After reading about it, I wondered what you guys might think 'bout the whole thing. Personally, I find it kinda scary that we could be alone in the universe...

Given the size of our universe and that scientists have discovered other planets that are very similar to ours, I wouldn't be doubtful that other places may have life, and if they do in fact evolve like us I wouldn't doubt that the certain circumstances arise that other species become intelligent.

That hypothesis is inaccurate. There's bacteria on planets that we aren't able to live on ourselves, bacteria is life, which exists almost everywhere in our universe. There are other planets like ours out there, in fact there are some where the living condition are better, such as planet size that is more than ours with the same life support capabilities like Earth.

That's not what the hypothesis questions, it's if other life can become sentient.

Complex life, not bacteria.

Also: we can only see so far into the universe. I would consider that probably huge amount of galaxies, stars, and planets that we cannot see.

Do you even know what sentient means?

Beyond the known universe is a huge mystery indeed. For all we know, our corner of the universe is completely different to everything else ;-;

I want to know exactly what stars made me, that would be amazing.

What's sad is that our generation will probably never get to see things outside the observable universe.

That's the thing, though. "Probably" is still a probability. Considering how random everything is, we might have unexpected breakthroughs and we MIGHT get to see things outside the observable universe, maybe even personally..

Just stay positive, and keep an open mind :o

I don't know about this whole life and space thing. Couldn't life be vastly different from what we know. I mean we only have experience with one planet. I imagine life on other planets could have completely different needs in other parts of our universe.

Silicon based lifeforms would be a close second to carbon. That opens up many more opportunities for life.

Yeah, I mean other organisms could have a very very different way of working. But I doubt we will ever find out in my life time.

If this is true then it is very likely that there is/was life on mars.

Maybe asteroids aren't natural and an alien planet launches them to make more planets with life
