The story we have all heard from movies, television, newspapers, and most magazines and textbooks is that dinosaurs “ruled the Earth” for 140 million years, died out 65 million years ago, and therefore weren’t around when Noah and company set sail on the Ark around 4,300 years ago.
However, the Bible gives a completely different view of Earth (and therefore, dinosaur) history. As God’s written Word to us, we can trust it to tell the truth about the past.
Although the Bible does not tell us exactly how long ago it was that God made the world and its creatures, we can make a good estimate of the age of the universe by carefully studying the whole counsel of Scripture:
1.God made everything in six days, and rested on the seventh. (By the way, this is the basis for our seven day week—Exodus 20:8–11). Leading Hebrew scholars indicate that, based on the grammatical structure of Genesis 1, these “days” were of normal length, and did not represent long periods of time (see Get Answers: Genesis).
2.We are told God created the first man and woman—Adam and Eve—on Day 6, along with the land animals (which would have included dinosaurs).
3.The Bible records the genealogies from Adam to Christ. From the ages given in these lists (and accepting that Jesus Christ, the Son of God, came to Earth around 2,000 years ago), we can conclude that the universe is only a few thousand years old (perhaps just 6,000), and not millions of years old (see also Did Jesus Say He Created in Six Literal Days?).
Thus, dinosaurs lived within the past few thousand years.
