Here is a couple of paragraphs from a dear book of mine and I thought maybe some of you would like to comment.

If stars evolve, we should see about as many star births as star deaths. The deaths of stars are bright and sudden evets called supernovas. Similarly, the birth of a star should be accompanied bt the appearance of new star light when comparted with the many phtographic plates made decades earlier. Instruments should also be able to detect dust falling into the new star. Actaully, the stars that some astronomers believe are very new are expelling matter. We have never seen a star born, but we have seen hundereds of stars die. There is not evidence that stars evolve.

Stellar evolution is used to estimating the age of the stars. These age estimates are then used to establish a framework for stellar evolution. This is circular reasoning.

Any comments - just curious?
