But that doesn't mean all opinions are equally valid. Any opinion that the universe to be 10,000 years old can be dismissed as invalid.
Nor did I say they were, nor did I say anything about how old the universe is, did I? Why do folks insist on any subject in creation other than the OP, is it because they know they cannot answer the questions with empirical evidence so they feel the need to deflect to another subject?
I would never try to convince anyone that is not open to Christian scriptures about the universe because I absolutely believe that if God Himself stood before them and performed supernatural miracles, they would still not accept anything He may say until science could prove it.
