I agree with much of what you say. But the length of time is way off. It is secular timelines based on speculation and misinformation. The Bible record is clear that the earth is only about 6,200 years old. See http://www.albatrus.org/english/theology/creation/biblical_age_earth.htm.
I tend to lean towards the following explanation regarding biblical timelines though I understand that there are differing schools of thought.

Quote from: Shlomo Riskin
The Bible is not interested in conveying literal and chronological facts in its story of Creation. After all, the sun and the moon were not created until the fourth day, and it is specifically their movements which are the determinants for our 24-hour day. Beyond any doubt, then, yom (day) in the context of the seven days of Creation cannot mean a literal 24-hour day.

Maimonides, in his Guide for the Perplexed, interprets all biblical stories until the advent of Abraham as allegories, whose purpose is to convey moral lessons
...
And this certainly leaves the door open to maintain that One thousand (or one million) years in Your eyes is like one day [Psalms 90:4]. Each biblical day in the Creation story may well represent an epoch of thousands or millions or years.

The biblical site I linked above, shows only 6,200 years back to the time of Adam and Eve. The word "day" means 24 hours because of the included "evening and morning." The only time that is not clear is the time before the creation of light. The electromagnetic spectrum might not have been in existence before then. We don't know if time had the same meaning before light was created.
If the Hebrew word for the first "was" in verse 1 of Genesis really meant its other meaning "became," then there might have been untold ages prior to the earth becoming formless and void. But we know nothing of these, since everything was formless and void when God started making things on the earth that existed since the time that He created light.
The question is, why would anyone lean towards the idea that the earth was much older than 6,000 years? If it is because of what science and the media say, the scientists tell us themselves in their papers that they are not sure. It is the media and the universities that have made up the whole idea of millions or billions of years.
