How do you know soft tissue cannot be found in dino fossils that are millions of years old? Why do you believe that?
Yes it is science itself which has disproved the idea that dinosaurs are millions of years old with a single test. Otherwise soft tissue can last millions of years. Do you think soft tissue can last millions of years? I don't. I think it's much more likely that dinosaurs aren't millions of years old at all. Either way, science was wrong. So now the latest scientific discoveries have proved that what scientists have been teaching about the dinosaurs is completely wrong, just like when the idea of a heliocentric solar system replaced the earlier scientific theory of the geocentric Ptolemaic system. Those who cling to outdated and discredited theories such as the theory of evolution are like those who would not accept the evidence that the Earth revolved around the sun. People who "believe" science don't understand science, they just trust that the scientists must know what they are talking about. That's not too smart. People who think for themselves are skeptical and question everything.
