heathen,
: no I don't think they will find life on mars ,the environment is too hostile with extreme cold and poisonous gasses I couldn't see a planet such as mars capable of supporting biological life as we know it
Then how to you explain the existence of life forms in your average Kingdom Hall?
Farkel
Actually, evidence of water has been found in Martian meteorites. Granted, its not actual liquid water droplets such as what has been found in various ordinary meteorites but alteration that can only be caused by water acting on those rocks. Also, from what I've heard and seen is that everyone should be watching the news for stories about a new Mars rock that was recently found in Africa.
Also, Mars really isn't that unfriendly of a place. Granted, you definitely would not want to go on vacaction there but bacteria has been found in less hospitable places here on earth. Not only that but Mars hasn't always been as inhospitable of a place as it is now. Some of the data coming in from Nasa's studies of Mars suggest that at one point in time there may have actually been seas of liquid water on Mars. Not only that but earth was a very inhospitable place for quite a long time in its early history. Mars, however, became a nice place to live long before earth did. Not only that but since Mars is closer to the asteroid belt it would get more impactors from that asteroid belt. Why is that important? Amino acids have been found in various meteorites, carbonaceous chondrites to be exact. There are a relatively small number of them on earth despite the fact that carbonaceous asteroids are by far more plentiful in space. The reason for that is that they are very friable and don't survive their passage through the atmosphere nearly as well as other types of meteorites.
So what am I getting at?
There was more material in the asteroid belt in the earlier part of our solar system's history. More material containing the amino acids that are needed to form life. Mars was a more hospitable place than earth was back then plus it also had a thinner atmosphere which means that the friable carbonaceous chondrites would have a better chance of surviving their trip to the surface.
Basically, Mars starts off as a more hospitable planet in addition to the fact that it got hit with more material that could help form life so the question really isn't about the chance of life on Mars, it should be how is that life bloomed more readily on earth instead Mars?
Jesus, can you post a link regarding the Nakhla meteorite? LOL, I feel silly asking someone who walked on water if they can post a link, but I mean would you mind?
I used to wonder that if God created angels and mankind, why would we (JWs) think he was incapable of creating some other sort of life form that could live on Mars or some other planet in the vast universe. It used to make me think that an all powerful God was limited by our (JWs) own limited interpretations of the universe and sheer vanity.
Here's a good site containing information on all the Martian meteorites. The guy who runs this site is just an super nice guy.

Also, if you want another, more in depth, site check out

On the left hand side click on "Achondrites" and then scroll down to Nakhla and click on it. Actually, any of the meteorites listed under the "Shergottite," "Nakhlite," or "Chassignite" there will be information about Martian rocks. This is probably the best informational meteorite site out there. If you have any questions you might not want to bother writing the guy because he tends to be a bit of a jerk, IMO. What's cool about this site though is that all meteorites shown are from his private collection. Yes, you can actually own pieces of meteorites, even Martian ones. Some are more expensive than others but you can still purchase them if you feel the desire.
if there was life on mars what the hell happened up there
Same thing that will happen here. Planets cool down after time - the cooling causes the tectonic activity to slow down, then finally stop. Once it's stopped, the planet is 'dead' - the regurgitating, basically, of elements from volcanic activity keep a fundamental process of life on the planet going.
In short, a planet must be geologically active to also be biologically active.
Mars apparenly 'cooled down' faster than earth (we're not talking about surface temperature here - the core temperature of the planet is what is the concern here - which is determined by things like: the planet's size, the mineral composition of it, distance from the sun, etc.)
There is, of course, some evidence of occasional active tectonics on Mars - and more evidence the planet used to be quite active. Which means it is almost certain life, of some kind, COULD HAVE existed there. It does not now, of course, but it COULD HAVE - and that's enough to go looking.
the environment is too hostile with extreme cold and poisonous gasses
Ummm...with all due respect....
The temperature of a planet and its atmosphere have absolutely nothing to do with the possibility of 'life'. Life 'as we know it', sure - but that's the fault of our limited frame of reference, nothing more. There are probably LOTS of different environmental conditions that could lead to self-replicating molecules that evolve in to 'higher organisms'. We just haven't found any yet.
Granted, you definitely would not want to go on vacaction there but bacteria has been found in less hospitable places here on earth
Ding ding ding! True story. There are some pretty damn nasty places on this planet that life - even 'life as we know it' - exists just fine.
Thanks, JC, that was some very interesting stuff... I guess the jury is still out, but the case for early life on Mars has a lot more to it then I knew. Thanks again!
You're welcome Spider. If you, or anyone else, wants to talk more about this type of thing feel free to start a new topic as I find discussions such as this to be quite interesting.
the face on the Mars is looking nagry, as th WT is not available for him

Sorry you don't like my opinion Xander, but I seriously doubt that they will find life on mars and you didn't convince me of anything .Nobody has ever proven that amino acids can evolve into living organisms and I have read some scientific evidence that is more conclusive than what you have stated to the conditions on our planet versus other planets and the significance of all the necessities for supporting and maintaining life .So I am sticking with my conclusion . LoL @ farkel .that's a different circumstance there.
