Note: I didn't post it in the other thread just so everyone can easily notice this message.
There is already enough evidence to prove that humanity, the -blam!- sapiens, were never, and could never, have been the forerunner species. Humans have already brought out enough experiments and scientific research to know, well enough, the history of our planet and the life upon it.
After the big bang had occurred and our planet brought out development, the atmosphere was way too harsh for any living organism to survive. In addition, it was also way too [b]hot.[b] The Earth’s early atmosphere contained hydrogen cyanide, carbon dioxide, carbon monoxide, nitrogen, hydrogen sulfide, and water.
About four billion years ago, Earth cooled enough to allow solid rocks to form. About 3.8 billion years ago, Earth cooled enough for water to remain a liquid. How did we find out how organisms came about upon the planet? It was no Adam and Eve. It all started from the amino acids that came from the lightning and the substances within’ the atmosphere. We found this out from Miller and Urey’s experiment.
Since I don’t have my main resource to explain how their experiment worked, I’ll leave you one from tidepool.st.usm.edu:
In 1953, Miller and Urey tested the "Oparin and Haldane* hypothesis1 by attempting to simulate in a closed system devoid of living organisms the conditions presumed to exist on the early earth's surface. They found that by subjecting a mixture of gases (water vapor, hydrogen, methane and ammonia) to energy, a variety of amino acids and other organic compounds were synthesized in a few days. Numerous replications and modifications of this experiment in many laboratories have yielded similar results. Chemicals formed include all 20 amino acids, sugars, lipids, the purine and pyrimidine bases found in nucleic acids and ATP (when phosphate is also present). These results are obtained as long as oxygen gas is not present in the reaction mixture. Results of this experiment caused a new era of experimentation and analysis of possible primordial components. Coupled with this were the new important discoveries by astrophysicists of the presence of organic molecules in the interstellar medium and in meteorites. However, at present, the relevance of the experimental results of Miller and Urey are being questioned, since the atmospheric conditions used in the experiment are not thought to accurately reflect those of the early earth.
This hypothesis stated that conditions on the primitive earth favored chemical reactions that synthesized organic compounds from inorganic precursors.
AKA Lightning + Early Atmosphere = Amino Acids.
Anyways, after this, we have enough evidence from microfossils and fossils, and using relative dating and radioactive dating upon those fossils, to know the complete history of life. From the time where life first came upon earth, to our present time – therefore in conclusion, there’s no possible way the forerunners can be the humanity species.
Hey thanks darwin, but i agree with that other guy halo doesnt corespond to our planet. IT IS JUST A GAME... i cant believe i just said that.
