I referenced Psalm 90:4 in the article, but here you go again...
Psalm 90:
1 Lord, thou hast been our dwelling place in all generations.
2 Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.
3 Thou turnest man to destruction; and sayest, Return, ye children of men.
4 For a thousand years in thy sight are but as yesterday when it is past, and as a watch in the night.
5 Thou carriest them away as with a flood; they are as a sleep: in the morning they are like grass which groweth up.
6 In the morning it flourisheth, and groweth up; in the evening it is cut down, and withereth.
7 For we are consumed by thine anger, and by thy wrath are we troubled.
8 Thou hast set our iniquities before thee, our secret sins in the light of thy countenance.
9 For all our days are passed away in thy wrath: we spend our years as a tale that is told.
10 The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labour and sorrow; for it is soon cut off, and we fly away.
11 Who knoweth the power of thine anger? even according to thy fear, so is thy wrath.
12 So teach us to number our days, that we may apply our hearts unto wisdom.
13 Return, O LORD, how long? and let it repent thee concerning thy servants.
14 O satisfy us early with thy mercy; that we may rejoice and be glad all our days.
15 Make us glad according to the days wherein thou hast afflicted us, and the years wherein we have seen evil.
16 Let thy work appear unto thy servants, and thy glory unto their children.
17 And let the beauty of the LORD our God be upon us: and establish thou the work of our hands upon us; yea, the work of our hands establish thou it.
Verse 4 is interesting, because the surrounding verses reference Creation, Salvation, and the Flood.
Also, take note of verse 10, where 70 "days" is used figuratively to mean 70 "years."
The reference of time when God is speaking either is an absurd number, like the billion you mention, or it is a number Humans can grasp and understand. God uses the long time period of 1000 years being equal to a day because it is a metaphor used to speak of God's willingness to wait for us to repent.
As seen in Psalm 90, that's just not the only possible context for that metaphor. You are asserting an interpretation that is far too limited, simply to uphold other limited interpretations.
This passage has NOTHING to do with Creation at all!! Those who use it to defend some long term age or whatever are misusing the verse. It is clear that this reference to 1000 years is about God's mercy, not the creation of the world in any sense at all.
In what literal sense is the 1000 year equation being applied to humans? None of us live to 1000.
The sense being used is a poetic sense describing the Eternity of God. That sense of God's Eternity is intrinsic, not merely an aspect of His mercy.
