One of the difficulties I run into when discussing 6 literal days of creation is in what happened on the 7th day where the same word for day,
yom, is used (Gen 2:2), 'On the 7th day God finished his work that he had done, and he rested on the seventh day from all his work that he had done'. This may sound a strange question: For how long has God been resting on the 7th day?
Also, we find in the creation story (Gen 1 and 2) that 'day' (
yom) refers to more than a 24-hour period. When speaking of whole of the 6 'days' of creation, what do we find Gen 2:4 stating? This verse speaks of 'the day' (
yom) when all things were created.
While
yom is most often used to refer to a 24 hour period, but this is not an absolute meaning. This idea is confirmed in passages of the OT like Psalm 90:4 (ESV), 'For a thousand years in your sight are but as yesterday when it is past, or as a watch in the night'. So from God's perspective, a thousand years are like a day (yesterday) or a night watch (short period of time). Ps 90:4 is cited in 2 Peter 3:8, 'A day is like a thousand years'.
St Augustine of Hippo did not accept 6 literal 24-hour days of creation. See
The City of God (
Bk 11, ch 6) where he wrote, 'What kind of days these were it is extremely difficult, or perhaps impossible for us to conceive, and how much more to say!'
As for a global flood or not, I accept that it was global as Scriptures state, 'And the waters prevailed so mightily on the earth that all the high mountains under the whole heaven were covered' (Gen 7:19 ESV). That sounds universal to me.
These are Dr Norman Geisler's arguments for a universal flood:
This topic has so many aspects that could be debated back and forth.
