Reasoning steps: Age of the earth and days of creation

Verdicts: T3 · Age of the earth and days of creation. Method: conventions, scoring and proximity eras. Scripture is the primary measure; fathers are weighed by era (Era I to c. 150 = 1.0, II = 0.8, III = 0.6, IV = 0.4).

T03.1: Days of creation and the age of the world

Step T03.1.1: Scripture

Gen 1 numbers six days, each with ’evening and morning’; Exod 20:11 grounds the Sabbath in them. Gen 1:14 places the sun on day four, which early readers already noticed. Genre and the meaning of יוֹם are debated.

Step T03.1.2: Patristic evidence

Basil (Era III): ’evening and morning … never exceeds the space of one day’. Augustine (Era III): ‘what kind of days these were it is extremely difficult, or perhaps impossible for us to conceive’ (he held an instantaneous creation), yet ’not 6000 years have yet passed’. Sources: basil-t03-s1 · augustine-t03-s1 · augustine-t03-s2.

Step T03.1.3: Weighing decision

The fathers agree the world is young (under about 6000 years, by biblical chronology) but split on the days: ordinary days (Basil) vs a non-literal, instantaneous creation (Augustine). Verdict: young world (consensus); nature of the days split.

• Confidence: Medium.

Step T03.1.4: Source-proximity weighing

• Scripture (benchmark): Six numbered days with evening and morning (Gen 1; Exod 20:11); genre questions leave room for debate. (Scripture confidence: low-medium)
• Assessment: Era III only. Scripture’s plain wording favours ordinary days; Augustine shows an early non-literal reading.
