Stars can be grouped into two general types called population I and population II. The criteria for classification include space velocity, location in the galaxy, composition, differences in distribution on the Hertzsprung-Russell diagram, integrated color, and the presence of nearby dust and gas. The current evolutionary theory of stellar evolution and galaxy formation succeeds in giving a qualitative explanation for the population types. In establishing a creation model of stellar (and galactic) astronomy, it is important to keep in mind the two different populations.If an alternate model is to be taken seriously, then the observed population types should be explained in a very plausible fashion.
