Also, remember carbon-14 dating, which is primary in giving us billions of earth years, is built on presuppositions.
Yeah, the same kind of "presupposistions" of nuclear physics and nuclear chemistry that led to the discovery of nuclear fission, nuclear power, and linear accelerators to treat cancer, for example...ALL are realities.
Carbon-14 helps date objects up to about 50,000 years old, not "billions of earth years". Potassium-argon and uranium-lead dating methods help date objects much older.
