This has been on my mind for awhile, and me and brother got in a huge debate over this yesterday. We were taught in school that the dinosaurs became extinct 65 million years ago and that the Earth is 2.4 billion years old. I really find these things hard to believe. How do scientist really know this? I know we have tools like carbon dating and stuff like that, but who came up with it, developed it, and programmed these machines and computers to help us answer these question? The reason why I ask these questions is that there is more and more evidence that the dinosaurs aren't as old as we make them out to be. There are cave paintings of pictures of dinosaurs. About 4000 years ago man drew what they saw, so how can they accurately draw a stegasaurus? These drawings and paintings are found all araound the world. These photos are quite obvious that man knew about the existance of dinosaurs and the only way man knew about dinosaurs was because they lived with the dinosaurs. Between 4,000 - 6,000 years ago our lands were supposedly sort of one land mass, and animals and humans lived a longer life than we do now. Unlike humans, reptiles continue to grow until they died. So if you have a baby stegasaurus that survives for 200 years, that animal would be huge at the time of it's death. Also scientist have been caught destroying evidence like these, and fossilized footprints that proves that man and dinosaur walked this Earth together. That just makes me sick. Scientist are supposed to find and search for the truth, and not destroy evidence. Obvisouly the reason behind this is to protect science 'facts'. This type of evidence disproves the theory of evolution and everything that we know about dinosaurs. Did Man Walk With Dinosaurs I am trying my best to not start a religious debate on this and the link I provided is from a religious site but doesn't use any religious context. What do you think? Do you think dinosaurs could of acutally existed only 6000 years ago, or do you believe what we have already been taught? Discuss.
