We have been subject to fraudulent education of many types for decades. You might sit down with your bright grandson and investigate his claims. I encountered this and found that recent tests have shown soft tissue in dinosaur fossils, verified under electron microscopes, even reports of smell on some fossils, The scientists reporting have been fired, banned from publishing in major journals, etc as nothing is allowed but to repeat the evolutionary theory and age time of Darwin and Lyell, a seminarian and lawyer respectively. Regardless what a great chance you have to really spend time and bond with a brave little boy who is not afraid to challenge the socialist thought pattern which requires strict allegiance to evolution
