i finished the BBC's 5 part miniseries Earth: The Biography and in episode 4, Oceans, it says scientists believe up to 1/2 the water in our oceans came from meteorites , which are mostly rock, metal and ice. like in 2005 they crashed a space probe into a meteor and it released 250,000 tons of water.

here's a clip from the episode about the ocean conveyor, which they say if the ice melted it would stop this which would poison the oceans and stop 1/2 our oxygen production which comes from phytoplankton and if this conveyor stopped it would mean the death of more than 90% of forms of life on earth

it's a really great series.

it also says 2 continents colliding blocked off a water passage which redirected becoming the gulf stream and because of this flow is why we have our ice caps on the poles

and i forgot where but this special specieis of jellyfish, the golden jellyfish, lost about 70% of their numbers from the water raising just 2 degrees in temperature.

it also brings up that things change throught the planet's immense history but the difference is we are pumping greenhouse gases and taking away the oxygen producers (like deforestation and polluting the water) at such a massive rate it's not giving the planet enough time to compensate and adapt and ends on the note of we don't need to worry about destroying the planet because it may take many years to adpat itself again, as it has throughout it's history like the meteor that hit in Mexico that caused the death of the dinosaurs, what we need to worry about is destroying ourselves

    Of course we are aliens.


    We are aliens to other aliens! Did that just blow your mind or what??!?! :lol:

    ive always thought the earth would simply regenerate herself when mankind manages to kill himself. tis us that have to fear ourselves. earth will look after herself as she always has done.
    hear my name
    take a good look
    this could be the day
    hold my hand
    lie beside me
    i just need to say

    Well technically, everything came from the same place during the big bang if you think about it. It's all relative.

    no, i'm saying maybe at least some animals or reptiles came something in a comet or meteorite. hey, a lot of people think some white guy with a beard twitched his nose and created every thing!

    you should watch the miniseries, Earth: The Biography, though, it does a great job of showing how all these things, even Jupiter, balance each other to make life sustainable for us and the different cycles of the earth that weren't sustainable for something like us or fish.

    Outside of some bacteria, don't think anything living (as we define it) would survive the vacuum of space or the heat or re-entry.

    one of the links i posted said life can survive for a few years in the vacuum of space. the atmosphere and entry into it is a good point, although i forgot what the series said the state of the atmosphere was at the time the oceans were created. obviously large objects CAN survive the atmosphere, or could at 1 time, since a meteor impact caused the extinction of the dinosaurs

    "This profound discovery implies two startling probabilities. Firstly, if a component of protein can be found in local space, then it is possible that life on Earth started, received a boost, or was altered in some way by impacts from interstellar bodies such as comets.

    "Glycine is an amino acid used by living organisms to make proteins, and this is the first time an amino acid has been found in a comet," said Dr. Jamie Elsila of NASA`s Goddard Space Flight Center. Dr. Elsila is the lead author of a paper on this research accepted for publication in the journal Meteoritics and Planetary Science. "Our discovery supports the theory that some of life`s ingredients formed in space and were delivered to Earth long ago by meteorite and comet impacts." This idea was first proposed in the '60s when glycine and other amino acids were found in a number of meteorites. According to Dr. Elsila, the most famous one landed outside of Murchison, Australia in 1969."

    also:

    Recent studies on ALH 84001 have shown that, although chances are low, eventually, Martian rocks such as ALH 84001 could actually transfer Martian life to Earth.[12] Bacterial spores, and rock dwelling organisms are speculated to survive in space for 5 years, meaning transfer of Martian life to our planet is theoretically possible.

    I suppose that the atmosphere would have to had been in place for the oceans to form. Proteins and their ilk are not life...they are the building blocks of life. Yes, life (as currently defined) could evolve with the aid of these components. The vast majority of life found on Earth requires O2 to live, that said, there is bacteria or archeobacteria that does not require O2....that is the unknown life that can sustain itself in the vacuum of space.

    yes, the atmosphere would have to be there but it has changed throughout the planets history and still is, like certain clouds that only form at certain heights are starting to form lower....it had an entire episode on the atmosphere but i don't remember much. it's a really good 5 part series.

    i wonder what that article means by "rock dwelling organisms"

    edit:



    An endolith is an organism (archaeum, bacterium, fungus, lichen, alga or amoeba) that lives inside rock, coral, animal shells, or in the pores between mineral grains of a rock. Many are extremophiles; living in places previously thought inhospitable to life. They are of particular interest to astrobiologists, who theorize that endolithic environments on Mars and other planets constitute potential refugia for extraterrestrial microbial communities.

    Surviving the journey
    Can microorganisms survive long exposure to the space environment? This question is of paramount importance for the transfer of viable microorganisms from one planet to another, since even dormant organisms might not be able to survive a long trip. Furthermore, cosmic rays, ultraviolet light or even radiation from the enclosing rocks might kill the organisms along the way.

    Many microorganisms stand up surprisingly well to the space environment. Subjected to high vacuum, some bacteria quickly dehydrate and enter a state of suspended animation from which they are readily revived by contact with water and nutrients. Medical laboratories routinely use high vacuums for preservation of bacteria. Viable microorganisms were recovered from pans of the Surveyor 3 camera system after three years exposure to the lunar environment. However, these instances of preservation have only been tested over times approaching decades, not over the tens to hundreds of millions of years necessary for interplanetary travel.

    Nature, however, has been kind enough to give us several instances of really long-term preservation of viable microorganisms. Chris McKay of NASA Ames Research Center has extracted microorganisms preserved for perhaps as long as 3 million years from deep cores in the Siberian permafrost. Even more impressive is the discovery of bacteria that were preserved for some 255 million years in salt beds of Permian age discovered at a site in New Mexico. Dehydrated by contact with salt and protected from radiation by the salt's low content of radioactive elements, these ancient bacteria demonstrated their viability by causing the decay of fish that had been packed with the salt.

    Living bacteria can tolerate extremely high radiation doses, far higher than any multicellular organism can withstand. They can resist the effects of radiation largely because of active DNA repair systems. It is less clear that a dormant bacterium could tolerate large amounts of radiation. However, if the microorganisms happened to be living in cracks or pores of rocks that were ejected as large blocks, the rock itself might provide adequate shielding against both cosmic rays and ultraviolet light. Since it requires about 3 meters (about 10 feet) of rock to shield against high-energy galactic cosmic rays, if the impact event were to throw out rock fragments of about 10 meters (30 feet) diameter or larger, a significant interior volume would be protected against this radiation. Ultraviolet light can be screened by only a few microns of silicate dust, so the interiors of large ejecta blocks might be excellent havens for spacefaring bacteria.
