Do you believe in extraterristial life? Why or why not?

Answer 1

Well, I have absolutely no scientific back-up for my theory. It's just my word for it, but yes, I believe so.

It's just hard to believe, that of all the planets ANYWHERE in the universe, only Earth has life. To me, that's just not probable.

There's a lot of eyewitness accounts for aliens and whatnot, but I would say 99% of that is a load of crap.

Answer 2

I dont personally and just because its a big universe doesnt mean that there has to be other intelligent species out there, like everybody says, "anything is possible." And this is why i dont believe in it:

1. Were alone. If not, where are they? No hard concrete evidence that there is.

2. Life-bearing worlds are extremely rare due to the lack of properties needed to support life.

3. We even try listening for extraterrestrial and yet have heard not a thing. Listening for extraterrestrial is futile and even scientist admit it.

4. We should have been visited by "aliens."

5. The galaxy shouldve been colonized by extraterrestrial civilizations if they exist.

6. Four reasons why no other intelligent species are on Earth at present time and they are: "Physical explanations, Sociological explanations, Temporal explanations, and that they were present at one time but no longer exist."

7. If you were to use the Sieve of Ferme formula, you would then be able to factor out all the planets and come down to a few planets that are possibly able to support life. Including Earth as one.

8. We happened to emerged by chance stated by a famous biologist called Jacques Monod, "evolution is chance caught on the wing."

Those are just my views and everyone has there own.

Answer 3

Of course we cant be the only planet with life in all the universe and wouldnt make any sense of why there wouldnt be. I also think the government knows more than what theyre saying because they have all these conspiracies nowadays it seems like anything could be possible. But if it would have it that we would encounter UFOs it would be something to remember with all the religions that might be questioning and other things so it would almost be a national catastrophe.

Answer 4

I believe there are aliens out rhere and there is a 100% chance the reason i say that is because there is no possible way you can go to a place that is never ending and not seeing a thing on the way it is like flying around the world and not seeing a animal,human,man made building and towers there has to be life .

Answer 5

it would be naive to think that replication of the events on earth that lead to the evolution of life won't happen elsewhere. the case of life on our planet is not so unique noting that water could be anywhere, a planet which could maintiain water in liquid form could just be out there. it's very possible. and we all know that water is vital for life to exist. and speaking about life, the range is too broad from sapient beings to bacteria.

if we are to consider the drake equation (plausibility of an alien life form having civilization similar or more advanced than ours that is on our galaxy alone) we have 0.00000001 probability. but also think how many galaxies our universe contain. for now the posibility of making the arecibo message known to other intelligent life forms is so small that is because intelligent life forms are too far apart in space or time. another reason is that we have not been searching long enough. and communications can still be technically impossible we may not be able to listen properly. so far the world's most advanced snooping program is SETI and it has its own limitations too. i can also say that probably they're just out there and they choose not to communicate because they are either non-technological or they're just too alien to react.

for now, there's an observable planet named Gliesi 581 c which is very earth-like. it has a lot of characteristic suitable in sustaining life. but it's just too far @ 20.5 LY. and back to our backyard solar system there is still an existing suggestion that mars, europa, enceladus and titan is capable of sustaining life more so still host primitive life forms the scale of bacteria. so small as they may sound still for as long as it is alive then we may never be so alone after all.

Answer 6

Not to sound like Spock, but belief is irrelevant. Life may exist outside our planet, or it may not. What you, I, or anyone else believes does not affect the existence or non-existsence.

You will even see people give probabilities such as results from the Drake equation, but that is purely guesswork. We have exactly one known example of a life-bearing planet in our universe. That is not enough stastical data to draw any kind of reasonable conclusion.

Again, belief is irrelevant. We only can accept the fact that we don't know.

Answer 7

I think that there is a very, very, high probability that there is life elsewhere in the universe. The known universe is just too big for there not to be.

As far as UFO sightings, etc, here on Earth, I don't know. If extraterrestrials are capable of visiting here, their technological capabilities would have to be far more advanced than humans are capable of producing at this time.

Answer 8

Life forms visiting earth? No. Life forms out on some planet in another galaxy? Yes. Do I believe they are intelligent? Possibly.

Answer 9

Yes I do why couldnt there be our government knows about this but doesnt want to tell us.I hered that in the 20s or 30s whenever they brodcasted War of the worlds it was kind of a test to see how people would handle this.Also in every fire station and police station they have a manual on how to deal with extraterristials if there is a crash or somthing.I think our government is keeping a lid on it.Because they think it mite disrupt peoples lives.Also the Catholic church wants to keep a lid on it as well.They think somthing like this would rewin their religion.

Answer 10

Absolutely. People shouldn't believe that we are the only planet with some sort of life.
