There are many paradoxes according to Darwinian evolution theory. For example, homosexuality is influenced by gene. The same sex sexual behavior provides neither reproductive nor survival benefit according to Darwinian theory. This is called a Darwinian Paradox. Hereby, we propose a better theory, named Sun Theory of Evolution, to explain the Darwinian Paradoxes like that. In the Sun Theory, animals cannot evolve into human beings. Humans are intelligent beings since the beginning of the time when the earth entered a stable stage. According to Sun Theory, the current human species, Homo sapiens, originated from a handful of survivors after a worldwide disaster, like a global flood or a destructive war. Moreover, this unique theory supports and extends the Albert Einstein's most famous proverb: "I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones." A severe war brought civilization down to the Stone Age, and human society had to restart again. Further, we proposed our new human evolution/civilization model, "Sun Model of Civilization". Based on the new model and novel theory, human has high-level of prehistorical civilization, a global disaster destroyed the records, and made it "prehistorical". Civilization may have repeating cycles, and this explains many abnormal observations. In Sun Theory, the Stone Age is around the bottom of the curve and is a gap period between two better civilization stages. It is a difficult age for humans, who go down to the bottom and survive in very harsh natural environments with minimal tools. It is noteworthy that it is extremely rare for a highly civilized human to become fossil, because he knows to avoid the dangerous marshland and the body is usually cremated when he die. This explains that there are lack of human fossils beyond the Stone Age. In addition, the current Carbon-14 dating, the major radioisotope experiment used to measure the archaeology time for human origins, is only reliable for up to 60,000 years. Further, radioisotope dating is not accurate if there are changes in environments, e.g. isotope deficiency in habitats, carbon ratios from nuclear activities and fossil fuel burning. Thus, the current dating methods are not ready to study human relics beyond the Stone Age. Unfortunately, such technical limits are often ignored because of the influences from the dominating belief, the Darwinian evolution.
