I grew up as a JW believing that each creative day was a thousand years each. Man was created on the seventh day and man's existence on earth was supposed to have been six thousand years back in 1975.
However, this WT article on reconciling science and the Bible says something different that I never picked up on in my later years as a JW. (I guess I blocked it out better than I thought)
For example, when we understand that the Bible uses the term "day" to represent various periods of time, we see that the account of the six creative days in Genesis need not conflict with the scientific conclusion that the age of the earth is about four and a half billion years. According to the Bible, the earth existed for an unstated period before the creative days began. (See the box "The Creative Days—24 Hours Each?") Even if science corrects itself and suggests a different age for our planet, the statements made in the Bible still hold true. Instead of contradicting the Bible, science in this and many other cases actually provides us with voluminous supplemental information about the physical world, both present and past.
The "box" comment: Some fundamentalists claim that creationism rather than evolution explains pre-human history. They assert that all physical creation was produced in just six days of 24 hours each sometime between 6,000 and 10,000 years ago. But in doing so, they promote an unscriptural teaching that has caused many to ridicule the Bible.
Okay, was I confused when I thought (as a JW) that the earth was only several thousand years old? Are there any publications that actually say that a creative day was a thousand years? Are there any that claim that the earth is only thousands of years old and not millions? Did I sleep through every meeting I ever went to?
Also, according to this WT teaching the earth rock could have existed for millions of years before God decided to press ahead with his "creative days". How does that explain fossils that are millions of years old if he didn't create the flying/land creatures until what ever "creative day" he created them?
Any links to past publication quotes would be appreciated. I'd like to learn a little more on the evolution of the creation doctrine (pun intended).
