Do you think aliens exist?

Question

If so do you have any stories to tell about it?

Answer 1

As everyone has put it logic (and chances) dictate that there is life out there, that is the odds are just too great for there not to be life out there. The Galaxy is way to vast. Whether they be civilizations like in Star Wars or Star Trek who knows. Have you ever heard of Drakes Equation? It is a mathematical formula that shows that there are theoretically civilizarions out there. Lifeforms also can survive in places we think are inhospitible as well.

Case in point, while not extraterrestrial in origin, when Apollo 12 astronauts recovered pieces of the Surveyor 3 probe (which had been on the Moon for 2.5 years at that point it was discovered that bacteria that was on insulation when launched SURVIVED the voyage (vacuum radiation extreme cold and heat) as well as the similar conditions on the Lunar surface. After Apollo 11, 12, and 14 NASA put the Astronauts in Quarantine to ensure that the Earth was not contaminated by Lunar germs, curiously even after the discovery of the bacteria that practice was stopped. It really makes you think and wonder. Because of this discovery the thoughts of our contaminating other planets were taken more serious leading to the biological safeguards and protocols to protect Mars during the Viking and later programs. Maybe microbial life from other planets could survive on asteroids or comets and seed other planets. Maybe life isn't even like us but just microbes. Viking 1 + 2 "proved" Mars to be lifeless (despite encouraging results from Viking 1) these two missions and a handful of other missions have only tested a handful of Locations on Mars. The same with the Moon. There may yet be an Oasis on these lifeless planets.

Answer 2

Of course! We already know that there is water underneath the surface of Jupidors moon Europa, and because there is water there is most likely bacteria, and bacteria is the founding of all living lifeforms. The bacteria just need time to evolve. So if there are any other planets in any other galexies with water they either have or will have aliens. they may be microscopic, but they would still be forms of life existing on other planets.
As for a story, i have heard that scientists in antartica found an asteroid undreneath the snow which had fossils on it. Because of the fossils they aren't sure if it really is an asteroid or a rock from the sea a penguin brought on land, but it supposedly has all the properties of an asteriod.

Answer 3

I've never encountered an alien, but given the probability that we are all alone is absurd given how big the universe is. The odds are pretty good that the same kind of chemical reaction that started life on Earth 3 and a half billion years ago must have started on other planets and continued on. Chances are that there is another intelligent species out there wondering the same thing, and their civilization is just as messed up as ours.

Answer 4

Here, you figure it out using the Drake equation.

The Drake equation states that N = the multiple of seven factors, which are listed below:

N is the number of civilizations in our galaxy with which we might expect to be able to communicate at any given time and the seven factors, which we simply multiply together, are:

R* is the rate of star formation in our galaxy

fp is the fraction of those stars that have planets

ne is average number of planets that can potentially support life per star that has planets

fl is the fraction of the above that actually go on to develop life

fi is the fraction of the above that actually go on to develop intelligent life

fc is the fraction of the above that are willing and able to communicate

L is the expected lifetime of such a civilization

Drake, Sagen, et al. frequently use this equation to claim that, out of the billions and billions of galaxies with billions and billions of stars, there have to be other planets with life. The problem with that logic is that the values they plug into some of these factors are pure SWAG (silly wild *** guesses).

For example, ne (the average number of planets that can potentially support life per star that has planets) might be way lower than anyone previously thought. That is, life supporting planets may be much rarer than supposed. Thus far, in our search for extraterrestrial life, we've come up with nothing.

Answer 5

Yes, I think they exist but I do not have any informative or interesting stories to share.

Answer 6

I do have one little story that I heard when NASA sent soemthing to mars in the program called "MISSION MARS"
It said that they found a little wormy thing in Mars which was still alive.
I don't know if its true but that is what i heard.

Answer 7

I neither believe nor disbelieve.

I keep an open mind about such questions, as there is no evidence to support either side.

Do I hope there is? Again, if it is dangerous to humans no. If it will benefit us (and us them) then yes.

Answer 8

I think that somewhere in the universe, there is something else that is living. However, we will probably never see it and if we do, we may not even recognize it.

Answer 9

To quote Contact,

"The Universe is a really BIG place; if we are alone, it'd be an awful waste of space wouldn't it?"

Answer 10

sure, in all the universe whether you think it was created or just happened, you cant tell me that this is the only planet that accidentally spawned life.
