I do not claim I know or have certainty. I think that life on this earth, and the form to it, is thousands but not billions (American or British meaning) of years old, but the universe with the unformed planet that is now the Earth for us could actually be thousands of millions of years old. I still believe the Bible account then. There could be gaps in genealogy lists that might even be hundreds of years all together, but not many thousands or millions of years. It is not compatible with evolution of all life, as God made everything and it was all very good (the only place in the Bible anything is called that) and it was without suffering and death, as described, and the perfect goodness and power of God made it that way. Still the world before the acts of creation described in the account was formless, so it could have been there much longer than how long ago there was that creation week remaining formless. The evidences for the universe having been around for so much longer are too strong for me to see that can just be dismissed. But I can see dismissing evolution as nothing for it is overwhelming in evidence for me, that cannot be accounted for with perfect creation from God as described.
