The wrong information, repeated frequently enough often becomes accepted as fact. This is known as reinforcement syndrome. Many eminent scientists accepted that humans had 48 chromosomes, even if their microscopes said otherwise.
The same thing has happened with the supposed extinction of dinosaurs 65-million years ago. Much evidence suggests it's wrong, like historical accounts of dragons that sound like dinosaurs and the existence of blood cells and protein in dinosaur fossils.
According to Skeptics, one of the characteristics of a pseudo-scientific theory is that it contradicts a known scientific law. For instance, in biology, we have the law of biogenesis, which states that life only comes from life. Ironically, though, many self-professed Skeptics ignore this scientific law when it comes to the origin of life.
Scientists are increasingly recognising the catastrophic nature of the geologic record. This goes against old ideas of only slow-and-gradual processes being responsible for all the rocks and fossils. These new perspectives are much more in line with a Biblical view of earth history, whereby Noah’s flood wiped out all air-breathing land animals not on the Ark. No, there were not eight mass extinctions in earth history—but there certainly was one massive extinction event!
