This is a bogus ploy by the loony left to try and pidgeonhole Creationists as idiots who believe the Earth is only 6000 years old, or that Creation only took 6 days.
Neither is the case - and the true Scriptures never make any such claims.
The current "Bible" is a mere (and very loose) translation from the original Hebrew language. The translation was done at the behest of King James. And whenever the translators could not quite "fit" a proper translation, they made their own.
For example, the original Scriptures say the Earth was created in SIX TIMES, not six days. In ancient Hebrew, the same word (yom) is used to denote any period of time, from a moment to an eon. In fact, in Isaiah 30:8, it says "Now go, write it before them in a table, and note it in a book, that it may be for the time (yom) to come for ever and ever." In this case, Yom is equal to "forever." The translators needed to choose a specific timeframe in Genesis, so they chose DAY. But in reality, it could have been a month, year, milennia, age or eon. But nowhere does the original Scriptures say the Earth was created in 6 days.
As to how old the Earth is, according to the Bible, no one knows. But we do know that a liberal professor in the 1970's used the "six days" reference to determine the Earth was only 6,000 years old according to the Bible, and used his formula to discount Creationism.
In reality, and only assuming the professor was correct in his formula but incorrect about the 6 days, then it could be hypothesized that it was Adam & Eve that were created 6,000 years ago - not the Earth.
So, the liberals, atheists and other lunatics who choose to use the bogus "6 days" assumption only prove their own ignorance.
Further, and just to set the record straight, nowhere in the Bible does it say Adam and Eve were the first humans. On the contrary, they were only the first INTELLIGENT, MODERN humans. According to Scripture, God had already created man in His image during the 4th "day" (time). Adam was created after God finished, and took a "day" of rest. As further evidence, when Adam's son Cain was cast out, the Scripture says he went to the land of Nod, where "he took a wife." So, the Bible apparently recognizes that some form of Man was already resident on Earth. Still, libs and atheists insist on saying otherwise, because they need to discount Creationism in order to destroy Christianity that they may pursue their lives of sin and gluttony without recrimination.
The next time some liberal or atheist moron hits you with the "6 days", or "6,000 year old Earth" crap, you can now set them straight.
