Who, Why, What, Where, When,

and How• All of these are philosophical questions

• Only the Blue ones What, Where, When, and How are generally falsifiable and therefore scientific questions.

• Tonight we are essentially focusing of When Creation was!

• We are assuming there was a beginning, that assumption does have some evidence, though.

Galileo and fossils

• Chapter 11, Fossils, in “The Eye of the Lynx: Galileo, His Friends, and the Beginnings of Modern Natural History” by David Freedberg © 2002 University of Chicago Press. Fossilized wood, iron concretions, and ammonite fragments found in what is now Italy by the Linceans founded by Frederico Cesi in 1603.

• Since things are much more ancient than letters, it is no marvel if, in our day, no records exist of these seas having covered so many countries. . . But sufficient for us is the testimony of things created in the salt waters, and found again in high mountains far from the seas.

Age of the Universe

• Timeline of the Big Bang

• Age Crisis no longer a problem but was an estimation problem in astrophysics in the 1990s.

• Big Bang maybe a poor term, but we seem to be stuck with it.
