***The days in Genesis can be interpreted no other way, than 24 hour periods. How can an era or age or span of time have an evening and morning?***
A good question. 2 Peter 3:
6 7 But do not ignore this one fact, beloved, that with the Lord one day is like a thousand years and a thousand years like one day.
which brings us to Psalm 90:
2
Before the mountains were born, the earth and the world brought forth, from eternity to eternity you are God. A thousand years in your eyes are merely a yesterday,
Each era or age has a beginning and an end. In poetical form, the beginning of something is often called the dawn or morning and the end the dusk or evening.
***Plus, a day is defined as one rotation of the Earth on its axis, so any claims about no Sun till the 4th day are irrelevant. ***
No. The ancient Israelites defined a day as that time from sunset to sunset. Therefore each day is not exactly as long as either the previous or the next.
Joshua 10:
12
On this day, when the LORD delivered up the Amorites to the Israelites,
Joshua prayed to the LORD,
and said in the presence of Israel:
Stand still, O sun, at Gibeon,
O moon, in the valley of Aijalon!
13
3 And the sun stood still,
and the moon stayed,
while the nation took vengeance on its foes.
Umm, how long was this day? Not 24 hours, I assure you.
Excellent points.
