I can't stand it!!! Get some larnin', please? Would you like to show a link demonstrating that anyone has ever witnessed a spontaneous nuclear explosion, not started by man? Ha! Don't have one do you? Therefore that "proves" that stars are not nuclear explosions, right?
You expect things to happen on a human scale that exist at several orders of magnitude less often than you expect them to happen. You don't like comet impact theories either, yet you were lucky enough to be alive at a time and place where humanity had the ability to WATCH such an impact on Jupiter. That was really remarkable, actually. Had it happened only 50 years ago, we wouldn't have been able to see it.
If you care to reverse your ignorance, here are some links

How does evolution occur? The two main mechanisms are mutation and natural selection. A mutation is any change in the DNA base sequence (genetic information) of a gene. However, only heritable mutations, such as those occurring in the gametes (reproductive cells) or the cell lineage contributing to gametes, are involved in evolution [Cos: by the law of probability, gametes are a small number of the total cells. Assuming that the risk of mutation is about equal, then gametes have a very small chance of getting the mutation AND still being able to fulfill their roll. However, with million or even thousands of individuals each reproducing, it can happen. There are natural mutagenic compounds. Do a Google search if you want to find them]. Such mutations can result from many factors, including natural background radiation and viral infection. Because only a small portion of the genetic sequence of the DNA molecule is used to code for proteins, most mutations do not result in new traits. Of the mutations which do result in new traits, most are harmful. That is, they interfere with an organisms physiology or in some other way reduce an organisms adaptability to its environment. However, sometimes just by chance, a mutation will occur which produces a trait that leaves an organism better adapted to its environment. Natural selection is the process by which, organisms best adapted to their environment tend to survive and increase in numbers, while those less well adapted tend to be eliminated. In most species, only a small fraction of births result in survival to adulthood. Individuals in a species which are best adapted, have the greatest chance of reaching adulthood and have a tendency to survive longer as adults than less well adapted individuals in that species. Therefore, the best adapted individuals in a species will have a tendency to produce the most offspring as well. In this way, natural selection allows for species to adapt to changing environmental conditions.
