The age of stars can be calculated fairly easily and very accurately, actually. I am not an astrophysicist, so I can not give you the formulae used. But I do know that they are fairly accurate. Saying that the age of something can not be proven is technically true. But, scientists never try to prove the exact age. They try to get the best estimation possible, and are rather good at it.

Something just popped into my head about this subject. How do you, or I, know that they are accurate in their calculations on how old a star is? They could easily say that this star is 1 Million years old and no one would really know the difference, because no one is going to question it; besides other scientist who are studying the same star. But still, how do the scientists themselves know if they are correct in their calculations? They don't know if their formulae is correct in figuring the age.
Just a thought.

I now return you to your topic and me lurking in this thread.
