When we understand that the word "day" Hebrew can mean an Age or a year or any suitable duration of time, it is clear that the facts of science support understanding these first seven days of God as the seven Eras:
The word day (Hebrew,
yohm; Greek,
he·me´ra) is not confined to just 24 hours in the Bible nor even among people, for we at times say in our "grandfather's day", meaning decades of time. The six "creative" days in which Jehovah God used to prepare the earth for human habitation at the end of the 6th "creative" day, were not 24 hour periods, but several thousand years long. At Genesis 2:4, all six "creative" days were now called just one "day".
Also, what the apostle Paul wrote to the Hebrew Christians provides support to the long length of several thousand years of a "creative" day. At Hebrews 3:7-11, Paul is quoting from Psalms 95:8-11 concerning the rebellious Israelites not ' entering into God's rest." Then at Hebrews 4:1, Paul now says that the Hebrew Christians have the opportunity of "entering into his rest", connecting with God's seventh "creative" day at Hebrews 4:4. Thus, over 4000 years later, God's "rest day" or the seventh "creative" day was still ongoing, being uncompleted.
In addition, all six of the previous "creative" days had closure, for each of them was completed with the expression: "And there came to be evening and there came to be morning, a ------ day."(Gen 1:5, 8, 13, 19, 23, 31)
However, the seventh "creative" day was never closed, and hence still ongoing to it's completion. We are still within the seventh "creative" day or God's "rest day". It's closure is still yet future, till all that Jehovah has purposed for the earth has been fulfilled, which is to have the earth finished as a paradise with only "meek" ones living on it.(Matt 5:5; Ps 37:11, 29)
It is an
inheritance from God for those who are "meek" or teachable by him. Psalms 115:16 says that "as regards the heavens, to Jehovah the heavens belong, but the
earth he has
given to the sons of men." Proverbs 2:21, 22 says that "the
upright are the ones that will
reside in the earth, and the
blameless are the ones that will be
left over in it. As regards the
wicked, they will be
cut off from the very earth; and as for the
treacherous, they will be
torn away from it."
