The existence of God

"The Earth...its size is perfect..." Let's start with "perfect distance" and uniqueness. Habitable zones are not stable. They are dependent on what life stage their sun is currently in. Stars go through three stages that could foster life. Our Sun is currently in a period, called the "main sequence", and the Earth lies within this stage's habitable zone. When our star begins to burn its hydrogen in a shell around a growing helium core, it brightens and expands and becomes a sub-giant. The inner edge of this zone remains habitable for several billion years while the outer extreme, where Saturn currently orbits, is habitable for a few hundred million years. The star then fluctuates in brightness for about 20 million years as it switches to burning helium almost exclusively, before becoming a red giant and swelling to 10 times the diameter of the Sun. For around a billion years afterwards, the habitable zone around the red giant extends from 7 to 22 AU, the outer edge of which lies beyond the orbit of Uranus. The time where these conditions change is large - long enough for life to form (compared to Earth - an estimated 700 million years). http://www.newscientist.com... "Therefore, the Earth is made specifically for life..." Our solar system: Venus was once capable of possible life before rampant greenhouse production. Mars has clearly been shown to have water formed canyons, waterfalls, rivers. Saturn's moon, Enceladus, Jupiter's moons, Ganymede and Callisto have shown to have water and organic compounds. Comets are known to contain ice and organic compounds that were necessary for life to begin on earth. http://www.astrobio.net... http://www.newscientist.com... http://www.newscientist.com... http://www.newscientist.com... http://www.msnbc.msn.com... http://www.newscientist.com... Uniqueness - also improbable. There are close to 10^11 to 10^12 stars in our galaxy, and there are perhaps 10^11 or 10^12 galaxies. Meaning there are roughly 10^22 to 10^24 stars in the Universe. 25 percent of Sun-like stars have planets. This means there are at least 100 billion stars with planets in our Galaxy. With about 100 billion galaxies in the observable universe, suggesting that there are at least 10 trillion planetary systems are in the Universe. http://arxiv.org... Earth: Clearly also not made for life - 99% of all known species are now extinct. Indeed, before our distant ancestors fled Africa - they too almost reached extinction, having a population of an estimated 2000 members. http://arjournals.annualreviews.org... http://elanso.com... "If we were to accept the fact the Earth supports life.." Abiogenesis: The pre-biotic environment was largely composed of basic fatty acids; under a range of pH they form vesicles which are permeable to small organic compounds. A vesicle encountering any free fatty acids will incorporate these (growth is driven by thermodynamics). Vesicles divide through mechanical processes - the pre-biotic environment and had basic nucleotides some which spontaneously polymerise. Monomers will base pair with a single stranded template and self ligate. These too can polymerise to form new templates or expand existing ones. A polymer due to surrounding ions will increase ionic pressure, stretching the vesicle membrane, again through simple thermodynamics. An encountered vesicle with fewer polymers and can be absorbed. Any vesicle that contains a polymer which would self replicate faster, will grow and divide faster, and become dominant. Any mutation that advanced rate of polymer replication would be selected for i.e. mutation plus natural selection accounts for increased information. "The universe, our galaxy.." The universe is largely driven by forces that are not random. Assigning probabilities on that assumption are worthless. Additionally - he conditional probability of the universe being as it is, given the existence of observers to notice it, is one. The lists of supportive conditions are irrelevant in supporting a designer - all fall under the false presumption that human life is a goal and additionally assume uniqueness in a largely unexplored Universe. Of note however.. "Unusually circular orbit of the earth" Orbit is elliptical. "Axial tilt and eccentricity of orbit" It's circular and eccentric? "The presence of an "impossibly" large moon" Its presence would indicate its lack of impossibility. :D "Slowing rotation makes advanced life possible" Which indicates nothing of a designer - or life for that matter. "All other earth-sized planets will be either completely deserts or water" Lol. Try again. Mars, Venus - and that's just in our solar system. "The need for Jupiter-sized planets at 5 AU from its star" Also not unique. :D. Current modelling estimates arrive at a rate of 25-50% of extra-solar planetary systems will have a habitable zone capable of supporting an earth like planet. Jupiter sized planets are also the only ones we are able to spot at distance due to their effect on gravity.. "Now according.." See above for probabilities. Your error is that human life is the benchmark. Evolution is not that certain were we to rewind and start from an earlier point again that humans would again arise. "Could blind luck or randomness create Earth.." Neither. Luck is irrelevant - the universe does not run on randomness. Size of Earth rubbish is basic anthropomorphic error - that human life is a goal. The universe doesn't care if there is life or not. "The alternative to God existing is that all that exists around us came about by natural cause and random chance." Natural yes, random no. "Could an electrical blast of lightening .." Someone's seen too much Ben Stein. Read above for basic Abiogenesis. I can add more in further rounds. "Would you expect life.." Big Bang formed from a singularity - not a vacuum. "Wouldn't it be more logical.." No mistakes? Read above for how close we came to not actually existing as a species. Arguments from ignorance are also not logical and neither is faith. "Advances in molecular biology have revealed .." Genetic information certainly doesn't require a designer. Read Abiogenesis section. "the universe is ordered by natural laws.." What would an unordered universe look like? False assumptions being that the universe 1. Can exist without naturally forming order - which contradicts your randomness assertions - and that a universe with different degrees of control would be wholly unacceptable to both the universe and life existing. "Another source of conviction.." Fallacy - Appeal to Authority. Quote mining. *tsks* "How did the Big Bang take place?" Fallacy - Argument from ignorance. A singularity is a quantum state; quantum theories are where you should be looking. "If energy cannot be created or destroyed.." Contradicts both your required first cause clause and the fact that you assert the universe has a beginning - which includes time and space. A being outside both those dimensions by definition cannot interact within the set universe. The fact *you* can't understand the Laws of Thermodynamics doesn't make your personal assertions any more valid. :D "We'll all familiar with Albert Einstein.." A singularity is of near infinite mass.
