I understand why people believe the earth isn't round ....because those desk globes are not originals.
Denying the existence of dinosaurs is the ultimate example of cognitive dissonace, outright denying of observable reality.
We don't just have their mineralised remains, but have found their footprints. They lived, they walked.
Genesis 4 says that the earth was formed, then Adam was made..... then he named all the the created animals, the NT tells us this was 6000yrs ago. Reality proves this impossible.
If we dig down into the earth, going backwards in time, we never find animals from different ages anywhere but in their time layer. This defies so much of what the religious fundementalists believe.
