I suggest reading the Introduction & Ch.’s 2 & 3 - focusing on the earth as a data recorder.
"The Privileged Planet” by Guillermo Gonzalez and Jay W. Richards. Gonzalez obtained a BS in 1987 in physics and astronomy from University of Arizona and his Ph.D. in astronomy from the University of Washington in 1993. He has done post-doctoral work at the University of Texas, Austin and the University of Washington. He has received fellowships, grants and awards from NASA, the University of Washington, Sigma Xi, and the National Science Foundation. Richards has a Ph.D., with honors, in philosophy and theology from Princeton Theological Seminary. He also has an M.Div. (Master of Divinity), a Th.M. (Master of Theology), and a B.A. with majors in Political Science and Religion. They provide an argument for the unique qualities associated with Earth that allow it to not only record it's own history but also The Privileged Planet consists of three main sections. Section One (“Our Local Environment”) considers planet Earth, the solar system, and Earth’s location in it. Section Two (“The Broader Universe”) looks at the stars, the galaxy, and the universe from the vantage point of Earth. And Section Three (“Implications”) considers what follows from the information considered in the first two sections.
In the "Stuff to Blow Your Mind" Part 1, I'd suggest starting at the 32:00 minute mark. The first 1/2 hour is their opinion/critique of religous texts and I don't feel they are relevant to our talk. After the 32 minute mark they focus on the different ways natural sciences have approached their estimate of the age of the earth.
The difficulty for many Christians studying the age of the Earth is reoncilling Genesis Chapter 1 with the determination by the science community that the Earth is approximately 4.5 Billion years old. The podcasts below offer alternative interpretions of Genesis Chapter 1 that allow for a much older Earth than the literal reading of 7 days in the book of Genesis. If you have time to listen to these, I suggest doing so in the order shown here:
