I am asking how anyone knows these characteristics of the various stars are indications of stages in their age. How do you know that Sol is at "a certain stage." How do you know that a red giant is a further stage of development? I am suggesting that the various ages assigned to stars is mere speculation. I don't see how it can be otherwise. There are no ancient records that a particular red giant was once a yellow dwarf (There couldn't be, of course, if the vast ages speculated for stellar development are correct). So what evidence is there for the supposed stellar development? I have never encountered any at all. Astronomists have offered a theory to explain the different varieties of suns (stars). And people simply accepted the theory with zero evidence.Hi TK, you wrote:Paidion-
I am not sure I understand your question 100%. If you are asking how we know that stars go through an aging process that takes a super long time, part of the answer must be that we see stars in different stages as I outlined. For example, our star (the sun) is at a certain stage (yellow dwarf). As the hydrogen fusion decreases it will ultimately become a red giant which will eclipse the orbits of Mercury and Venus. If earth still has life then it won’t survive. The fact that there are red giants observable means that those stars have been burning a lot longer than our sun.
What's wrong with an alternate speculation that all the stars were created to look much the same as we see them now? It's not that if the latter speculation is true, then God must have given them an appearance of age. For we don't know what "the appearance of age" is!
The latter speculation contradicts the former. Of that there is no doubt. But to accept the former speculation as fact with no evidence at all doesn't make sense to me.
