LFES FAR FLUNG RAW MATERIALS

Christopher Chyba has the leading idea that these space particles did in fact bring in the
planet's water and atmospheric gases. These space organisms are thought to be responsible
for making our earth habitable by bringing in water and gas molecules which would provide
our atmosphere and oceans. Also, that the space debris was needed to build life and could
have even started the first cellular processes. These space molecules could have absorbed
UV-rays from the sun, helping out the weaker molecules, and converting the light energy
made into chemical food, which is essential for photosynthesis. Miller showed that the
planets first single celled organisms came from a process of chemical steps which is
possible for the building blocks of life.
It is stated that everyday, tons of space dust falls to the earth's surface, some found
containing 50% organic carbon, bringing in about 30 tons of organic material. So not only
do some scientists argue about space particles bringing in water and gases, but they
could also bring in ready-made-organic molecules such as the ones seen today. From the
meteorites that hit the earth they were able to find a variety of 70 amino acids, but
only 8 are used by living cells to build proteins. These meteorites also show such
compounds including: nucleobases, ketones, quinones, carboxylic acids, amines, and
amides. Astronomers have seen a variety of these organic compounds in the universe and
more abundantly in clouds. 
An experiment was done in a laboratory by Allamandola, where he developed a cloud
containing such compounds seen in meteorites. This provided more evidence towards the
theory of the earlier development of earth. With the presence of such extraterrestrial
compounds like amino acids, quinones, amphiphilic molecules, and other organics, could
have very well made it possible for the development or helping towards the development of
such life processes.
In conclusion, it is easier for us to believe that extraterrestrial compounds were
present during the time of this evolution and that it inhibited the creation of such
living organisms. But since this concept is relatively new there is not enough evidence
to determine if such compounds had anything to do with the development. Why couldn't one
say that the scientists misinterpreted the development of earth and living organisms all
together? This assumption could regenerate all new findings as to when and how the earth
began.
