I'm sorry I just don't interpret the bible as saying anything about the earth being more than 10k years old.
Because the Bible is a history of the last 6,000 years. They call this written history. So we are talking about Genesis chapter one. Gerald Schroeder PhD MIT in Physics says that there are over 200,000 books in the Harvard library that explains the first 31 verses in the Bible. Yet we know that the age we live in began around 12,980 years ago. Because Peter and Moses tells us that 1,000 years is a day. This is why the KJV people use the word replenish. There was something here before that needed replenished. Because the earth was formless and void, basically in a state of ruin. Yet the OEC people find a different meaning for when the Earth itself was first formed. Both YEC and OEC are accurate in their understanding. Even if their understanding and interpretation of the exact same verse is different because the Bible has many layers of meaning.
God is infinite. All the books in the would could not even begin to explain the meaning of the word "beginning". Because God knows the end from the beginning. Isaiah 46 "Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my." We are told: "He chose us in Him before the foundation of the world, that we would be holy and blameless before Him." (Eph 1:4) How could God chose us to be holy and blameless in Him before there was even a world? David tells us (139:15 psalm) "all my days were written in Your book and ordained for me before one of them came to be." How could God write a book about every day of our life before we were even born?
In Isaiah 24:1 we read: "See, the LORD is going to lay waste the earth and devastate it; he will ruin its face and scatter its inhabitants--" God can tear down and build up. He can begin whenever and where ever He wants a new beginning. Jesus is the Alpha and Omega, the beginning and the end. God has no beginning but there are lots and lots of new beginnings here on the Earth. So I would not limit God in what HE can do and in what HE has done. Far to often we limit God and we do not take full advantage of all that HE wants and has for us.
We can see a parallel between the first 6000 years and the second 6,000 years. Just like we can look at day seven and see the 1,000 year reign of Christ contained within that day. Just as God rested for a day after He created the Earth we shall enter into 1,000 years when we shall rest from our works.
