There are basically two kinds of meteorites, stony and iron. Some stony meteorites contain small glass spheres called chondrules embedded in their matrix. These chondrules have been found to contain a significant quantity of carbon, crystallized water and amino acids. It has been proven that the amino acids are not contaminants from earth since both dextro and levo forms exist in the meteorites, and only the dextro forms are present here on earth.8
Fred Sisler of the U.S. Geological Survey collected samples from the interior of carbonaceous chondrite meteorites and found that, after a long period of time under sterile conditions, some of the nutrient broths derived from these samples clouded over, thus indicating the presence of living microorganisms. At least one of these roused organisms is totally unfamiliar to terrestrial microbiologists.9
It has also been determined that about 0.1% of all material which has ever fallen to the earth is organic. This is one million times more organic than earth itself, since only 0.0000001% of earth's mass is organic. Therefore the concentration of organic material in meteorites is much greater than here on our planet.10...This is evidence that those organic compounds precisely necessary for the initiation of life on earth could have been imported here from elsewhere.11
It would also appear likely that for life to become established here on earth, a whole mass of protocells would have had to arrive at the same time, both because of expected attrition12...and also because of a certain interdependency which they might have had. The continuation of life appears to require some organisms surviving at the expense of others. The surviving protocells would have incorporated the break-down products of the dying protocells, thus beginning the process of natural selection.
Much of the material contained within all forms of life consists of cosmic trace elements that originated within stars. During their lifetime, certain stars transform hydrogen to helium and eventually form heavy chemical elements which are discharged into space if the star becomes a supernova. Our bodies, therefore, are constructed of fossilized debris originating within stars.13
Inorganic-related intelligence is diffusely and unevenly distributed throughout space, and is more concentrated in those areas containing matter-energy. Organic-related intelligence would also appear to be universal in origin. However, it still lacks the "smoking gun" proof that might someday be provided if and when contact with an alien civilization is achieved.
