Creation vs. Evolution.

My opponent supports creation. No win this debate, I must do a few things: 1) Show the earth is NOT young, 2) give evidence for evolution. 1. Evidence for an old earth The earth is about 4.55 billion years old. Using radiometric-dating methods, the oldest rocks are about 3.9 billion years old. A few rocks are believed to be even 4.1 billion years old, but those are very rare. Although these measurements do not necessarily mean the earth is that old (if we find an old rock that does not equal we are that old), however it established a limit for how young the earth can be. If we have rocks 4.1 billion years of age, the earth cannot be younger then that, the earth must be as old (or older) then any formation found on it. So, in reality, the evidence I gave above proves an old earth. My opponent’s 6,000-year claim is falsified because the earth CANNOT be younger then 4 billion years old, and might be older. With the lowest possible number set to 4 billion, my opponent already loses the age of the earth point [1. http://www.talkorigins.org...]. Wikipedia holds similar information. Using radiometric dating systems on lunar rocks and Earthly materials the earth is in excess of a billion years. The oldest rocks, recently found in Australia, are 4.4 billion years old. So, again, the earth cannot be younger then 4.4 billion years, negating the resolution [2. http://en.wikipedia.org...] Brent Dalrymple notes, “If the Earth, the Moon, and meteorites were not genetically related and of the same age, there would be no reason for their Pb-isotopic compositions to lie along the same isochron. This is convincing evidence that the planetary bodies, including the Earth, all formed about 4.55 billion years ago.” [3. http://www.talkorigins.org...] The earth is over a billion years old, the earth is over 4 billion years old, its about 4.5 billion years old. That’s a fact, and the resolution is now negated. 2. Evidence for evolution Remains of animals in sedimentary rock give great evidence for the theory of evolution. Many extinct species found in these rocks have transitional parts, for example the beginning of a fin or leg[s], and the next layer would almost always have a fully evolved leg or fin. In other words, a finished product. The fossil evidence is irrefutable and proves evolution. This picture explains the point: http://www.debate.org...; [5. http://anthro.palomar.edu...] Genetic changes also proves evolution. “The earth's environments are constantly changing, usually in subtle and complex ways. When the changes are so great as to go beyond what most members of a population of organisms can tolerate, widespread death occurs. As Charles Darwin observed, however, not all individuals always perish. Fortunately, natural populations have genetic diversity. Those individuals whose characteristics allow them to survive an environmental crisis likely will be the only ones able to reproduce. Subsequently, their traits will be more common in the next generation--evolution of the population will have occurred. This process of natural selection resulting in evolution can be easily demonstrated over a 24 hour period in a laboratory Petri dish of bacteria living in a nutrient medium. When a lethal dose of antibiotic is added, there will be a mass die-off. However, a few of the bacteria usually are immune and survive. The next generation is mostly immune because they have inherited immunity from the survivors. That is the case with the purple bacteria in the Petri dishes shown below--the bacteria population has evolved.”[5] Another diagram of the point, this time genetic changes: http://www.debate.org...; [Spura note 5] Another example: http://www.debate.org... [Spura note 5] CONCLUSION: --Earth is old --Evolution exists. Theodosius Dobzhansky once said, “[Biology] without that light [of evolution] it becomes a pile of sundry facts some of them interesting or curious but making no meaningful picture as a whole.” [6. http://www.pbs.org...]
