Do you believe there is life on other planets?

I believe the components necessary for biological life on Earth are incredibly common in the universe because we've already proven that. We've also proven that there are billions of galaxies with trillions of planets. Even if all the right pieces only fall into place rarely, the odds are that it has happened more than once. Has intelligent life developed elsewhere? That's a different question but again, the odds are good that over 14 billion years and trillions of planets, we are not the first, last, or only intelligent life that has ever existed. Can I prove it? No. Could I be wrong? Yes. Is it arrogant and stupid to believe some magic invisible sky fairy created all of this for humans? I think so.

[slatyb]

It's more than trillions, it's millions of trillions of trillions.

[uzumymw]

I do. Probably not very close-by, but at the very least somewhere

Overall it seems life is easy... to happen. It was an incredibly sort time after the earth formed 4.5 billion years to carbon detected from life forms. Maybe 4.1 billion years.

The least recent common ancestor was probably 4.2 billion years ago. So it happened quick and therefore not that improbable to happen again on exo planets

It depends on what you mean by "life on other planets". If you are happy with pond scum lifeforms absolutely. if you expect cat & dog level intelligence than maybe not.

Random mutations ending up with a cute tabby takes a lot of random mutations and that is a lot of years. Homo sapiens in modern form arose 300,000 years but the good achievements only started happening 10,000 years ago. if life means someone like us that's a lot of years.

Then there are extinction events. Our sun swallows us in 7 billion years. Plate tectonics stop in 1 billion and that will kill us too. The next glaciation has a good chance of killing us or knocking us back to hunter gatherers.

So life is easy but slow and intelligent life takes 4 billion but everything might end between 4 to 5 billion years. High prob of pool scum but low prob of intelligent life because of global extinction events.

[RavVid]

Some other extinction events

deoxygenation ~ 1 billion

Oceans evaporate ~ 1 billion too.

[Chazmatazz269]

Yes. The prevailing theory suggests that the universe is infinite and still expanding, even growing. It’s absurd to believe that a single planet out of an infinite number of planets could be completely unique in any way. Especially when you understand what life is. Not all life is humanoid, intelligent or even sentient. Right here on Earth we have discovered two microorganisms that can survive environments and events that would almost certainly kill everything else on the planet. Therefore a planet doesn’t have to be even remotely similar to Earth to support life as we know it.
Beyond that we have to consider that life as we know it is not the only possible iteration. For example, all life on Earth that we know of is carbon based. Theoretically, alternative biochemistries likely exist and recent research suggests that a process called autocalasysis is more fundamental to life than the base molecules themselves.
With all of this in mind, it’s just plain silly to suggest that life is unique to our tiny blue planet. Therefore, i believe it’s not.

[SeekerOfTruth007]

Yes and no.

I believe God created everything for a purpose, and from a certain point of view there's no reason to create 600 Sextillion stars in the Universe without putting something living on the planets orbiting at least some of those stars. I would be rather disappointed to learn that there was no life on other planets or other Stars.

I don't believe in random evolution: Neither physical evolution of the Universe nor Darwinian evolution of life. The laws of the Universe are logical and maximized, which means they never change nor fail. If the Universe was formed by accident, then we'd expect the laws to look like an accident. They don't.

Therefore I evaluation "habitable planets" based on "Purpose", because an actual Almighty God wouldn't just waste his time doing things for no reason whatsoever. He'd have a purpose for everything. That being the case, I reason that "habitable planets" either already have life on them, or else we are intended to migrate to those planets somehow in the future.

If everything has a purpose, then habitable planets are in fact habitable.

[genericname85]

i don't typically "believe" shit. but my rational would be: why would the earth be the only planet out of a next to infinite number of planet. but i think if there was life on other planets, it's probably so far away that we'd never know cause even just traveling to find the evidence would take longer than the entire lifespan of our species. and since that same is probably true for all other life that may exist, that could explain why we never saw life elsewhere if it even exists.

[Pohjolan]

Actually it might be possible to determine this by measuring the light reflecting off a planet.
Also it might be possible to have FTL travel for practical purposes. Physicians say that it will lead to time travel paradoxes but engineers know that one has to cross 0 to get to a negative.

[genericname85]

@Pohjolan yeah crossing zero to get to negative doesn't explain anything in this context and you can't know if the light emission or reflection happens for other reasons but "life".

[Pohjolan]

@genericname85
Look we don't need to travel from point A to point B in minus 5 hours when plus 5 days suffices.

[genericname85]

@Pohjolan how does traveling in minus 5 hours make any sense? Are you even reading what you're saying?

[Pohjolan]

@genericname85
It doesn't. Thus the time travel paradoxes.

[genericname85]

@Pohjolan dude what are we talking about? You lost me. I'm saying we can't realistically reach far enough places any time soon. That's all there is to it. I see no point in discussing time travel, cause that's far away from any realistic and practical approach.

[Pohjolan]

@genericname85
Not without the ability to manipulate gravity.
Point IS that we don't need time travel.
If some travel takes minus days in theory then we can can also have plus days in practice.

[genericname85]

@Pohjolan point is: we can't reach either way.

[Pohjolan]

@genericname85
How would you know?

[genericname85]

@Pohjolan cause currently we struggle even getting to the moon my dude.

[Pohjolan]

@genericname85
That is with conventional rockets. Ability to affect gravity would a breakthrough comparable to the Wright brothers first flight.

[genericname85]

@Pohjolan dude i lvie in reality. not in a fictional future.

[FreyaRed]

Yes. I think even in our solar system on Jupiter's moons, high in atmosphere of Venus or deep caves on Mars exist primitive life forms. For intelligent or more complex life we need to look a little bit further but I think not further than 200 light years.

[AviatorTom]

Considering the vastness of the universe, the billions of stars and planets out there, it is questionable to assume that Earth is the only planet with life on it in the universe.

The issue is that, considering the distances involved and the speed of light limitation, we humans may never get together with life on another planet.

[loveslongnails]

Nah, with an uncalculatable number of galaxies and planets in the cosmos, somewhere in the trillions of trillions, it's insane to believe there could be life on or in any one of them!! What an absurdly stupid notion !! We're not only the BEST there is, we're ALL there is !! Yeah!

[Staximus]

There's billions of stars in our galaxy alone, they can't even count them all. And there's probably as many galaxies in the universe is there is stars in the Milky Way. Out of all those solar systems, we can't be the only planet with life on it

[Drumlin2001]

Yes. Or rather it has existed or will do. There are numberless planets across billions of galaxies. Across billions of years past and future. Quite possible there's life out there, but whether we'll ever see it is another matter.

[slatyb]

In our solar system? No. Somewhere on one of the septillions of planets in the universe? Seems very likely. Somewhere in our galaxy? Also seems likely but we don't know and probably never will.

[Dargil]

The universe is too large not to believe that. But they are probably too far away for any kind of contact. So we might as well be alone.

[snermcger]

The most widely cited estimate suggests there are approximately 22 sextillion planets (22,000,000,000,000,000,000,000) in the observable universe.
Ya think there might be? lol!

[DryGermanGuy]

The statistical chances are very high. The question is, if it’s intelligent life, like shown in Men in Black.

[exitseven]

yes. probably not in this solar system but we are not alone.

[Berethor]

There is no proof yet for life on other planets, we might be alone in the universe.

[CuriousMufuxka]

There has to be. Most likely not in our solar system, but perhaps millions of light years away..

[UrLoveMocha]

Yes I do… I don’t believe it’s possible that humans are alone.

[LiamS95]

I doubt it but I suppose you never know. It's surprising how many things have become a reality from shows like Star Trek.

[strawberryapple]

Way before that. Dick Tracy had the first iWatch! 🤣

[LiamS95]

@strawberryapple True

[altaboy]

Most definitely! The universe is so incredibly large that I think it is impossible for it to be otherwise.

[YourExLover69]

Could be.. Life in the shape of bacteria or virus but not humans.

[Anonymous]

Perhaps if I flew a rocket ship to Uranus we could find out 🚀

[msc545]

I think it is more likely that there is life on other planets than that there isn't at all.

[beefcakebradybatson]

Yes, but Earthlings' stupidity keeps them from visiting !!!

[Anonymous]

Yes, I think so, but those planets are too far from Earth.

[robocop666]

there's loads of planets out there with life. The greys are from Orions belt.

[strawberryapple]

Yes! Where do you think duct tape came from?

[queenofcardio]

I dont think so

[beenherebefore]

Yes, but not in human form.

[DonaldDarko]

There just about has to be.

[FunkyMonkee]

Absolutely!! How could there NOT be?

[MikeMcMansion]

Is their life on the internet?

[jahaims]

Statistically there is

[Bowserforever]

I think it's unlikely we'll ever find it

[Twalli]

Life, yes, intelligent life, I'm unsure.

[blackeagle007]

There could. Just no evidence as yet

[Kingofkings1992]

It's a possibility

[Subtle_Luminescence]

I'm open to the idea

[Daytoday79]

Yes.

[zombiewoof]

Somewhere

[Mike_Hum]

totally.

[_Troian_]

Ye I believe

[CubaPirate]

Absolutely👽
