There are people that think that humans may be related to aliens,I don`t agree with their belives,but they may not be as wrong as one might think.

With the deep impact probe drawing much attention to cometry activity, there are people who think that life arrived on Earth on comets (mostly made of water ice) .

Life? well quite posssibly the building blocks (ie DNA, RNA, etc) . Nothing that would even remotely fall into the "advanced" category. But yes, It falls in the realms of possibility.

But I find it hard to believe that anything more than the building blocks could be there frozen in the water ice of a comet,after eons of exposure to hard radiation.


And how would advanced life survive the impact of crashing in to the Earth at several thousand mile per hour?

Ah yes, Panspermia.

I find it difficult to think that life itself came here via this mode, the radiation angle is hard to dismiss. However, I'm not sure what protection is afforded if such compounds and perhaps even primitive life were, for example, buried deep in the core of a comet? Still questions around this one, IMO.

Some microorganisms can exist in spores forms that can withstand quite large doses of radiation.

Here is a good bacteria strain to Google

But before they ended up on the astoroid they came from some place else. Such a theory only widens the gap of original creation.

Please people lets try to keep religion out of this one.
Yes I know that no one has said the R-word but we are borderline here I can tell.

Both creation and evolution are based mainly on speculation. You can not discus the beginning of all things without touching on both. Our personal biases are a part of our thought process. So I am afraid if you consider intelligent design to be a religious view you are only limiting yourself to possibilities and become trapped in your own paradigm.

Thats what I was afraid of.

If there ever was an ATEIST I'm it.
To many bad things happening in the world for me to......

Wait a second,now I'm doing it ...

Lets keep it real(AS IN SCIENCE).

NOT TRYING TO PREACH, BUT HAVE YOU EVER CONSIDERED THAT ALL THOSE BAD THINGS IN THE WORLD HAPPEN BECUASE NOT EVERYONE BELIEVES?
(SORRY FOR CAPS)
second I dont think they let you in the club if you cant spell it correctly.....Athiest.

light humor really, just playing around. Its Friday, gosh diddilly darn.

yes, lets keep the ever UNintelligent tripe of "intelligent design" out of this.

i don't subscribe to the idea of panspermia. However, spores can survive in space and it has even been discussed in some scientific circles that humans may ultimately venture into the farther reaches of space by developing a spore that carries human DNA.

The difficulty with these discussions is it is hard for people to see outside of the history of their own species.

Some more wisdom from you hyperactive?
let look at what collective wisdom you express!

oh please, don't use the old "appeal to authority" bit again.

intelligent design has been debunked time and again. All we ever see come from the ID camp is more rhetoric.

Also, do not forget people are a product of their times, of cultural evolution, of knowledge.

Do I think your list of people idiots? I would have to evaluate each individually in reference to their time period and culture. Since ID is a new invention of the creationists in an attempt to undermine advancement with a culture of suspicion, distrust, dogma, and intolorance.

now can we get back to discussing the original topic in a serious manner?

My point precisely. I just wanted to point out that in order to have intelligent dialog one must have respect for others opinions and belief. You do have a habit of calling others fools and I hope you will reconsider your attitude toward others. As I do enjoy most of what you have to say.

What I don't understand is why scientist seem to think that all possible life outside of Earth must need water and oxygen. If they live on other worlds they might need methane and sulfur to breath to stay alive. Why must possible life survive the same as we?

Intelligent design is based on religious faith. ID is not a scientific concept and does not belong in science class. I'm sure that those among us who embrace religious beliefs would not be very pleased if they were compelled to give scientific theories equal time during their sermons? This is blatantly mixing apples and oranges...not a good idea.

As to the question of life, we really only have life on Earth as an example for study. However, chemistry out in the cosmos still follows certain rules. There could be life based on some element other than carbon, for example, silicon but this is only speculative. I think that scientists haven't ruled out the possibility of life very different from that which we know.

Lilly,

Silicon is old hat...carbon dioxide by-products make much more sense.
At, least, I think so.

Which is unfortunate. New discoveries will be made. Each one likely to be more bizarre than the one that came before.

Scientists found silicon-based (and ammonia) "lifeforms" on Titan around June 30th of this year. That's not too old hat.

I found it. This is for all of you with an imagination...

http://www.indiadaily.com/editorial/3387.asp

Ah yes, India Daily...it's imaginative alright!

They articles around the world.

Nowhere except the Headline do they say they have found anything

ADD is a you know what. Ah, but that's what I get, LOL.

actually, one of the problems currently faced is that while we should be looking for signs of life based ariound different compounds, those that call the shots are enamoured with the idea of "another earth" the searches get narrowed down by the preconception that "our world" is the norm.

Comets filled with lif....hmmm?
Take a bacterial culture. Put it in a nuclear reactor for about 10,000 years. Maybe that would equal the amount of radiation that the culture would absorb over a billion years in deep space bombarded by cosmic rays.

Then check to see if you have anything like DNA left. My guess, you'd have a lot of organic compounds but nothing like a viable genetic code.

I'm not sure if there's a hard answer for this question, yet.

We're getting close though.

That is one of the most tiring statements in modern times, and I am sick to death of it. I don't have to have respect for others opinions, cultures or beliefs, and indeed many of them I not only have no respect for, but dispise. The only thing I have to have respect for is others right to have such opinions, cultures and beliefs. If any of them are illegal under our laws, they have no rights to them to respect either. Anyone who says that they have all that respect for something they don't themselves see any value in is either lying, or absurd.

I find that sometimes when people are loosing a debate the pull out this "lack of respect"card.

Try calling them HBs or woo woos and they are quick to use that against you,to get out off the topic.

They have no problem what so ever calling you a moron,or worse.

Sorry if Im off topic here...

You do on these forums. So either get over it or be banned from these forums in the near future.

I don`t know what that was all about,but back to the topic....

Here is a good point and link from another forum.

"The fact that such complex molecular structures could have survived in AHL84001 (even if they're not relics of living things) indicates that not all information is lost during an impact. As with most other processes, impacts are dynamic events, with lots of destruction and wiping out of established structures, but also events that preserve many structures that happen to be in the right place.

Sort of like documented situations where very fragile things, such as a mirror, a case of eggs, and a box of Christmas ornaments, have survived direct hits by tornadoes."

http://www.weatherwise.org/02ja.cerveny.html

IMO it's not the impact that worries me. Rather, it's the radiation that concerns me. I'm not sure where I stand on the subject of panspermia, except to say that I don't view it as impossible.

Space radiation may select amino acids for life.

"The work suggests the molecular building blocks that form the "left-handed" proteins used by life on Earth took shape in space, bolstering the case that they could have seeded life on other planets."

Hazzard! You're great! Awhile ago, I read a magazine article about this very subject... but for the life of me I can't remember what magazine it was in. Anyway, I wanted to bring up this very point on another site discussing this subject but I had no sources to cite! So, Thanks a bunch.
