LOL! I can't help it, my techer was Jewish.
Truly, Schroeder has broken the age of the universe into days, which I aver is entirely appropriate since reconciling Genesis 1 and physical evidence in nature was his objective - and God spoke Genesis 1 in terms of days and notably, the first day.
It is the observer problem again - I agree with Schroeder and assert we ought to be reading Genesis 1 with God as the observer, not man.
Your point about sun and vegetation does not hold if we accept that the Genesis account refers to the creation of not the physical realm alone, but both the physical and the spiritual realms (emphasis mine):
These [are] the generations of the heavens and of the earth when they were created, in the day that the LORD God made the earth and the heavens, And every plant of the field before it was in the earth, and every herb of the field before it grew: for the LORD God had not caused it to rain upon the earth, and [there was] not a man to till the ground. - Genesis 2:4-5
And out of the ground made the LORD God to grow every tree that is pleasant to the sight, and good for food; the tree of life also in the midst of the garden, and the tree of knowledge of good and evil. - Gen 2:9
He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God. - Rev 2:7
My assertion is that he was created in heaven, in the spiritual realm, and placed in the Garden of Eden there. His clock began running when he was banished to mortality in Genesis 3.
The sixth day from the inception space/time coordinates is a quarter billion years ago from our space/time coordinates (Scripture and inflationary theory and relativity.)
On the Adamic clock (our space/time coordinates) - the day in which Adam ate of the fruit of the tree of the knowledge of good and evil was the first 1,000 years of the 7,000 allotted to Adamic man the last 1,000 is Christs millennial reign to come. (Emphasis mine)
Rather, Adam died at age 930 in the first 1,000 year day according to Scripture which corresponds to Creation week. Or to put it another way, 6 days of creation plus 1 day of rest corresponds to 6,000 years of Adamic man plus 1,000 year reign of Christ on earth (the Messiah era.)
That is the Jewish interpretation (Sanhedrin 97a; Avodah Zarah Sa) of this Psalm attributed to Moses:
The way all of this reconciles beautifully is the assertion that the Creation was not just the physical realm, but the spiritual realm as well. (Gen 1:1) The Garden of Eden, like the Temple, is in the Spiritual realm (albeit in both cases there is a type in the physical realm.)
By tradition, the Jewish Kaballah was passed down orally from Adam to now and the secrets of it - in particular the powers associated with certain sounds - were never to be written. Some (but not all) of the Kaballist mysticism was recorded centuries ago - and even now some aver to reveal these ancient oral secrets.
But I do not dismiss the Jewish Kaballah out-of-hand because I lean on the indwelling Spirit to guide me into Truth. As an example, the teaching that the firmament is a boundary and not a geometric location per se is Kaballistic in origin. And that rings true in the Spirit. But the extension of it, that the firmament is the speed of light neither rings true nor false for me.
Likewise, I suspect that much of what has been captured for millennia in the pseudepigraphral manuscripts have their origin in this Jewish oral tradition.
Some of these are directly referenced in Scripture, such as in Jude others are carried forward in tradition. But in any case, the Spirit draws me to certain points in the pseudepigraphal books such as what provoked Abraham to be called by God, how Job got into a mess with Satan, the back story of Genesis 6 and the Noah Flood and so on. And likewise, I am drawn to certain teaching of the Jewish Kaballah.
