Is there really life out there ???

Question

Do you think that we are the only living beings in this universe when there are billions of galaxies yet unknown ??

Answer 1

I think that there are other life forms out there. I can't believe that God created such a vast universe and only but us out here. Now, as to when we will find them, or when they will find us, I don't speculate. I just know that it will happen one day.

Answer 2

almost certainly. as we learn more about our own biochemistry, we learn how simple the beginnings were. so given the huge number of solar systems in the huge number of galaxies, it seems hard for a chemistry to exist without the creation of some kind of life. the amount of time for the chemistry to develop into intelligent beings will likely remain 1-2 billion years. so are there beings right now? probably. with the universe being 13-17 billion years, the likelihood of life beginning sooner than or in parallel with our timeline seems high. what also seems likely is that we will not be in contact with them during our lifetimes because of the distances involved and the speed with which information travels.

Answer 3

different people have different oppinios.
so listen to all of them and then just pick one you like most,
or try and think about it yourself.

I am happy to tell you my oppinion, since you asked:

I do not believe in god as the creattor, like many others do, so I prefer the scientific approuch to this question.
We know only so much, so much we can measure.
That means, we only know our srorundings so well, as we can "see" them. Until today, we did not "see" any other life then on our planet. But that does not mean, there is no other out there.
Scientist can explain to a certain degree, how life begun on planet earth, and what circumstances life needs to start.

In our case its basically cetain chemical key elements, which form water and air, etc. and the certain distance between earth and the sun. We know, that if the distance would change just slightly, we would all burn or freeze to death.

Because there are so many galaxies, it is probable that there is some similar situation somewhere else, which would allow for some kind of life. We just cant look so far to prove it, we can just assume it.

Personally I am sure there is, and its so far, they can not see us as well :)

Answer 4

The easiest way to tell is to use the drake equation.
N = R* fp * ne * fl * fi * fc * L

where,

N = The number of communicative civilizations
R* = The rate of formation of suitable stars (stars such as our Sun)
fp = The fraction of those stars with planets. (Current evidence indicates that planetary systems may be common for stars like the Sun.)
ne = The number of Earth-like worlds per planetary system
fl = The fraction of those Earth-like planets where life actually develops
fi = The fraction of life sites where intelligence develops
fc = The fraction of communicative planets (those on which electromagnetic communications technology develops)
L = The "lifetime" of communicating civilizations

There are 100 billion stars in our galaxy. If even 1/1000 of them were sun like, There would be 100 million possible systems for there to be earth-like planets and intelligent life. There are also 125 billion galaxies in the universe. That creates an extremely large number of possibles places for life to develop

Answer 5

No, I do not think we are the only living beings in the universe. What would be the point of all those billions (actually trillions) of galaxies? To please us? Heck, you can't even see them without a telescope.*

*Except for the Andromeda on a clear night if you know where to look, and the large and small Magellanic Clouds (irregular satellite galaxies of the Milky Way) if you lived in the southern hemisphere.

Answer 6

YES it is life is there.
U know why Iam yelling because there is the possibilities tht we are only the Aliens from other planet have conquered earth.
Possibility that an asteroid frm other planet came hit on the earth .Some scientist believe tht this is where the life has begun on earth.
Life is there in our universe but u should more think tht in which form it will be

Answer 7

Could be. The universe is so huge that it seems highly unlikely that there isn't some form of life somewhere other than Earth.

Answer 8

I think there is other kinds of life out there. Because there are hundreds of more galaxies. And maybe there are planets in them, too. So there is life out there.

Answer 9

There are definitely little critters out there....there is no way the galaxy would be that big for just one planet of living things....that would be kind of pointless...

Answer 10

We would really be arrogant to think that we're the only life in the universe.
