That was a guess you "tard"(hint hint 6,000/10,000 years ago-would the bible say two different years?)
although Adam was kicked from the garden about 6,000 years ago, based on the information given in the Bible. So thats a pretty close estimate..There were approximately 4000 years which passed throughout the Old Testament, and it has been a little over 2000 years since Jesus returned to Heaven; which is recorded in the New Testament
But accorrding to some the age of the earth is 13, 021 years.
