No, I don't believe the earth was created 6000 years ago, but probably millions of years ago.
The Bible simply states “In the beginning God created the heavens and the earth.” (Ge 1:1) Just how long ago the starry heavens and the earth were created is not stated. Therefore, there is no basis for Bible scholars to take issue with scientific calculations of the age of the planet. Scientists estimate the age of some rocks as being three and a half billion years, and the earth itself as being about four to four and a half billion or more years. I believe there could possibly be millions of years between Genesis 1:1 and Genesis 1:2. This would be the pre-man era, and would include the periods of dinosaurs etc.
With regard to the six creative days of the Genesis account, these days refer not to the creation of earth, but with the arranging and preparing of it for man to live on it.
