Natural Selection isn't a hypothesis, either

Natural selection is a phenomenon, no different than erosion or tectonic uplift: a mechanistic process observed to occur in the natural universe.
“Since Natural Selection makes not predictions, it can not be proven or disproven, as such it can never truly be a scientific theory.”
>>Well, natural selection is predictive in the same manner taht erosion is. Erosion allows us predict how geologic features will change over time, based on average precipitation rates, relative hardness of stone, composition of soils, etc., and natural selection allows us to make predictions regarding what changes will occur in allele frequencies in given environments over time, based on the differential relative fitness conferred by the competing allele pairs. For example, if we introduce antibiotics into a population of bacteria that are heterozygous with respect to alleles conferring resistance, we can accurately predict how many generations it will take for the population to become homozygous for alleles conferring resistance.
“If you have a theory that no fossil gap or evidence can disprove, if you have a theory that makes no predicitions for future events, if you have a theory that fails the most basic tests of science, what you have is an explaination that makes you feel good, not a working scientific theory.”
>>Natural selection, again, isn’t a theory: is a mechanism which operates in nature and may be directly observed. Evolutionary theories, on the other hand, are predictive and are falsifiable.
“Here's a clue, if there are no numbers associated with it, it's probably not science, it's philosophy, and like most of the macroscopic biological sciences it's a game of catalogueing while whereing a lab coat, and very little rational explaination or scientific inquiry.”
>>Evolutionary change through natural selection can and has been mathematically modeled and found predictive. (google the Hardy-Weinberg Equilibrium)
