There may be (indeed, I think PROBABLY) is life on other
planets in other solar systems in this and other galaxies.
There may actually be life IN space (that is, in the partial
vacuum between planets), but it wouldn't be anything carbon/
water based like life on Earth is.
I suspect as soon as you get off this planet, you'll end up
stretching your definition of life to include chemical reactions
that we haven't even thought about.
See Carl Sagan's "Cosmos" (1970s, I think, but great still).

I believe that it is ubsurd to think that there is no other life other than on planet Earth. Think about it...our sun is just a star, whats to say that every single one of those stars we see in the sky doesn't have it's own set of planets orbiting it? And if this is true, then how can we believe that there are so many planets but we are living on the only one that has life on it? AS I said, it's ubsurd.

I think it's logical to say that in a universe that goes on forever there is some other life form. It would be arrogant to believe we're the only life out there.

We don't have a lot of data, but using the data we have, we can make a prediction.
We can estimate the amount of life by doing the following.
Estimate of how many sun like star have planets. (wiki - Extrasolar planets)
Using solar system models, and observation, estimate the chance each solar system has of a planet being in the "habitable zone" for organic life as we know it.
Using solar system models, and observation, estimate the chance of a planet within the "habitable zone" to be the size to support life as we know it.
Using solar system models, and observation, estimate the chance of a planet within the "habitable zone" and the right size, to have the chemical makeup of earth, to support life as we know it.
Using solar system models, and observation, estimate the average life span of a planet in the habitable zone.
Since we know that our planet formed formed life within (give or take) 1.6 billion years ago.
Use statistics to slap all of that together and tell me what you get.

YES, a few a here on earth but that's just to protect us from other life forms that would wish to destroy us. Apparently no other life form is permitted to come remotely close to earth or will be destroyed by our protectors. the comets and asteroids that come by earth are actually monitoring sats. unfortunately the one like the one that just passed us will strike earth around 2102. I suggest don't move your kids to Europe

There is the crew of the International Space Station. :-)
Seriously, we honestly don't know. Depending on whom you are listening to, we are either one among many millions of inhabited worlds or unique in the Universe. However, until we have more evidence, it's pretty much a guessing game.

probably there is. try to watch the show titled 'extrterrestrial' in the national geographic channel. It shows how life forms would look like in other planets.

Yes...somewhere...possibly on Europa, a moon of Jupiter...the surface is ice. but there is warm water under that.
Regardless, it is a mathematical certainty that there are other life forms out there...

yes i think there are other life forms out there in space... who knows we are the aliens for them...:-)
