is their life on other planets?

Question

have you seen one???

Answer 1

not on other planets but surely in the universe

Answer 2

We know that there are planets orbiting other stars (they've discovered a dozen or so), and while I think only one other earth-like planet has been discovered (it's easier to find a Jupiter sized planet at that distance), this certainly indicates that there are other earthish planets out there, and earthish planets are a good place for developing earth-like life.
You don't have to go as far as another solar system to look for off-planet life. The European space program found that the planet Mars produces a good deal of methane: which is something bacteria produce. Since there isn't any recent volcanic activity to produce that methane, there is a high probability that it is indeed being produced by bacteria. Mars certainly used to have running water, you can tell by looking at the pictures. While the current atmospheric pressure does not allow water to exist as a liquid on the surface, the water under the surface may be usable, albeit at a very slow rate. [The sorts of space suits NASA is developing for use on Mars certainly suggest that they take the possibility of life on Mars very seriously. If Mars were lifeless, then you could put together a kit that would keep you alive on Mars with gear that is available over the counter. Instead, NASA is developing the sort of space suit that makes the ones used on space walks, or on the moon missions, look flimsy.]
Then there is one of Jupiter's moons, which appears to be covered in ice, with liquid water underneath the ice. This also allows for the possibility of life-forms developing.

Answer 3

The universe is so vast that it is incredibly unlikely that the combination of factors that came together to make "life" is unique to our planet. The view that we are alone is possibly a hold-over from the pre-scientific worldview that the earth was the ONLY firm ground that was at the center of the universe, with the heavens a clockwork-like bowl overhead, with mankind as the crown of creation with dominion over the creatures and plants. The existence of life on other planets does not even enter such a view, since the understanding of planet-as-world is not defined.

Answer 4

I believe there is life on other planets. I've never seen what it looks like, but then no one else has either. Samples taken from various probes have returned with microbes that can be classified as containing life to some degree. Sentient life is yet to be discovered. BTW, I don't think ETs have visited earth. Whatever that phenomena may be, it is very likely centered on this planet. Knowing that life is on other planets is a matter of faith, but this time in something a little more solid, namely science.

Answer 5

No I've never seen one but if you imagine the vast expanse of space then you have to admit that it's at least possible. Stephen Hawking came up with a theory not too long ago to explain why we have never made contact with other life forms. His theory was that life on other planets never reach the technological ability for space travel because they destroy themselves first. Pretty much what we're doing to our own planet right now. Basically no life has evolved past a point where they can balance the technology with the safety of the planet.
I thought it was interesting.

Answer 6

I do believe there is life on other planets, because the universe is massive. Just because no one else lives on the planets here in the Milky Way doesn't mean they couldn't live in another solar system.

Answer 7

Nobody knows but it is a possibility that conditons similar to ours might be found in other places in the Universe. Then in some way the first cell could be produced by some type of accident and the rest would be a matter of mytosis and evolution.

Answer 8

I believe that the universe is just too damn big for their not to be life on another planet out there somewhere. I just don't think we've found it yet.

I don't buy all the UFO sighting and alien abduction BS though.

Answer 9

why not?? I've seen odd things in the sky sometimes, but I wouldn't be able to tell you whether I was imagining it or it was real

Answer 10

may beeeeee ,but i feel that my maths teacher may from other planet .
universe is vast .who knows
