god put dinosaur bones on earth to test our faith.
in other words, they never existed.
wow... another religious zealot...
Anyway, most scientists do agree that dinosaurs have evolved into today's BIRDS. Not just chickens. Obviously, the biggest difference is the size. 90 million years ago, for example, the amount of oxygen in the air was much less than it is today. Lower amounts of oxygen tend to facilitate massive size growth in animal populations. Since the air contains so much more oxygen now than 90 million years ago, animals have adapted to become smaller because giant lungs are no longer needed to sufficiently supply the body with oxygen.
More oxygen = smaller lungs = smaller animals.
