do you think if there were other life forms someone whould have found out by now?

Answer 1

They are out there I am sure of it, but why would they want to communicate with us? All we do is kill each other and our own planet. They are probably afraid of catching something from us.

Answer 2

doubtful that humans can find them at this point. People like to argue because other planets don't have the atmosphere, water and oxygen that they can not support human life! Obviously! However why are we humans so ignorant to believe that all life forms have to be human? The other life forms on other planets and solar systems may have a different molecular structure than we do! There is NO WAY that we could be this lucky. There is something out there but we are too ignorant to believe otherwise. It is possible we have come across other lifeforms but they did not thing they were life forms because it was not the same as humans.

Answer 3

No way...we've barely begun to search, and our technology isn't entirely up to the task...yet. Even the HST isn't very useful for this because it's optics were designed to see FAR, not to magnify (so it can see unimaginably distant galaxies, but NOT the Apollo landing sites on the moon).

Also. the e/m evidence for other life forms has to have had time to reach us, AND we have to be LOOKING for the right kind of evidence (data). The odds are, given that we've just barely begun to look, that we won't detect anything for a while even if there are 100s of civilizations out there...unless they're WAY older than us, which may not be the case.

A really great idea for you is to go get Timothy Ferris' video, "Life Beyond Earth". This is the best video out there that covers all of this and explains our present state in the search for extra-terrestrial life.

Answer 4

I don't beleive we would have found them, our technology is still too simple to do such a thing. The farthest we've gone is some of the outer planets. That's pretty much like living in Tokyo and having only gotten your feet on the ground after waking up in the morning. The universe is massive and our capabilities limit us greatly. They would have to find us, and many people, myself included, beleive that they already have and that the government is hiding the evidence from the general public. Maybe in several thousand years, if our technology improves as rapidly as it has in the past hundred years, we will find other life forms out there in their basic stages of evolution, or already evolved into sentient inetlligent beings that we could communicate with with out causing them mass hysteria. For now we will not do the finding, they will.

Answer 5

No, how would we know? We haven't even found all the life forms on our own planet yet!
The only way we could currently know if other intelligent life exists in the universe would be to find it ourselves, no advanced life form would make vast contact with us because we are socially primitive, crap, we can't even get along with each other! it's obvious if there were another advanced civilization we would view them as a threat.
There is a good chance that there are many other forms of life in the universe, with the billions upon billions of galaxies & solar systems, what's the chances of life only happening once (what's the chances of anything only happening once!) I think that if we found out we were the only life in the universe, that should truly be more amazing than finding out we are not!

Answer 6

As in extraterrestrial life? No. We've just started to be able to deduce the presence of planets about other stars. Looking at the bright side of the earth from relatively close up, you really can't see much detail (go to Google earth and try it out). Now imagine that image reduced to the apparent size of a pinhead held at arm's length. Even more difficult to discern any structure. Seeing detail on distant planets is much more difficult than that.

There are projects designed to search for radio signals from intelligent life--intentional beacons to the universe--but such signals are weak and it takes a long time to process the data. If you are interested in joining the search, you can contribute to the SETI@home project. Your computer will download chunks of the data and process them with the CPU cycles you are not using.

Answer 7

Yeah I’m sure that with the handful of people monitoring the skies from observatories, the Hubble telescopes inability to see planets that are not gas giants, and spaces enormous size people "whould" definitely know if there were other life forms in space by now.

Incase you can't tell, I am being sarcastic you putz.

Answer 8

It's not easy to detect evidence for life in other parts of the universe, even assuming that the aliens are intelligent and leave traces that we could observe.

Part of the problem is that what we have been searching for is really just aliens who are exactly like ourselves. After people invented broadcasting, those searching supposed that intelligent aliens must have radio broadcasting too. It seems not to have occurred to the searchers that the putative aliens might not broadcast at all (broadcasting is wasteful of energy) but perhaps instead use the internet!

If there are intelligent aliens, they're not going to be easy to find, and they may well be a lot smarter than we give them credit for.

Answer 9

Ryan, the problem is the vast distances. The nearest star to our Sun is about 41/2 light years away. A light year is about six trillion miles. It is the distance light can travel in a year. Additionally, the speed of light is supposed to be the absolute speed limit in the universe.

So at the speed of light it would take us 9 years to accomplish a round trip to the nearest star and communication would be so clumsy after a few months that it would be useless. When we finally develop a method to effectively travel faster than light I think we will find the life you speak of.

Personally I think we will find life to be the norm. I think we will find life of some kind in at least 10% of all the solar systems with a single mainline star.

Answer 10

You mean other sentient life forms, right?

If they do exist, I think is unlikely for us to have heard from them. Take a look at the Drake Equation (see link) and use the calculator. It will suggest that there might be 1000 civilization capable of communicating with us. But, where are they? If the are randomly dispersed across the galaxy, they my be too far away for us to have heard them yet.

BTW, it is very, very likely that there is microbial life on Mars.

Answer 11

New life forms are frequently found on the little space rock we live on. I read recently where a pristine ecological environment was located somewhere on one of the island nations in Asia where several new species of fauna was found. New species of sea creatures are often found in the deep ocean. If you have reference to alien space creatures, I believe that they, in fact, exist. Unexplained objects have been appearing in the sky as long as man has been able to record sightings. Why do you suppose our government has refused to acknowledge their existence? Do you suppose that to do so, would be to admit to an alien life form that is vastly more intelligent and technologically more advanced than we puny humans are?
