Are there other creatures on other planets?

Question

i read just a few weeks ago NASA or whoever dug up Mars and found ice like ice glaciers and they're believed that animals like on well...in Mars and i just read that Earth two of them as a matter of fact but much-much bigger than our planet do you believe there are other creatures on other planets and are they humans or something else......

Answer 1

Possibly, but things like single cell organisms probably. Probably no humanoids, like Dr Spock if that's whet you are suggesting

Answer 2

Do I believe there is life elsewhere in the Universe?

Yes.

When you consider the size of the Universe it is almost impossible to think it could be otherwise.  There are 100 billion stars in our galaxy alone and 100 billion galaxies.  Life is bound to have formed somewhere else.  Intelligent life less likely but still very probable.

Frankly if our planet is the only one in the whole of creation with life on it I find that not only a little scary but rather lonely.

That said life elsewhere will almost certainly look nothing like life on earth (movies they tend to be similar because they need human actors in the costumes and lack imagination).

Answer 3

Nothing discovered yet, but  I think in the near future they will find life in other planets.

Answer 4

I don't think earth has a twin but it would be very unlikely that there is no life anywhere in the universe except on earth.  

We have discovered forms of life on earth in habitats that no one expected to support life.  One common thing in all of these is water.  So... we already know that ther is water on Mars so that satisfies one requirement for life (at least for life as we know it).

The Mars mission (Pheonix lander) is digging into the soil near the Martian north pole.  It will take some time for the test results to be gathered and interpreted.  The results may not be conclusive, it may find that there are other compounds (chemicals) in the ice that are associated with life on earth but that would not prove that there are living things on Mars.  The lander does have a microscope so, if there are large enough simple living organisms (microorganisms like ameobas or protozoa) we might get pictures.  The microscope on board is not able to see bacteria.

Answer 5

NASA has not found life on Mars.  The Phoenix lander did find ice below the surface of Mars  near its north pole.

Ice means water.  But that does NOT mean life.

As for the rest of your question, well, I have to just guess what you are talking about.

The "I just read that Earth two of them as a matter of fact"  - your fact doesn't mean anything, so I'm not going to even guess what you mean.

The "much much bigger than our planet", again I don't know what you mean.  There are many planets that are bigger than Earth (4 in our solar system, and so far almost 300 around other stars in the galaxy).

Most logical thinkers accept that life is not only possible on other worlds but highly likely (due to the apparently common formation of planets around stars and the abundance of orgaqnic molecules in space).

But that life will have evolved under different conditions, so there is very little chance (perhaps 1 in a trillion) that life will look like humans or any other life on Earth.

Life on Earth evolved over 4 billion years through random genetic mutation and selection.  The conditions on Earth are so complex that it is not likely that those exact conditions:

- same amount of water, oxygen, iron, aluminum, nitrogen, and all the other elements on Earth

- same exact solar radiation and temperature

- same axial tilt for seasons

- a large moon to stabilize the rotation and keep the atmosphere from becoming too thick

Too many variables to even consider they would be exactly duplicated on another world.

And even if the exact same conditions existed on another world, evolution and the development of life is random - the number of possible combinations for DNA are much greater (by billions of times) than the actual number of combinations used in all life on Earth.

Answer 6

in the visible universe, there are approximately 750,000,000,000,000,000 solar systems. think about that. what are the chances life is limited to one solar system... one planet for that matter. and keep in mind there are countless number of galaxies with solar systems in the part of the universe we can't see.
