The National SAFEKIDS Campaign recommends that no child under the age of 12 be left at home alone. However, consider a child's age and maturity level. For example, if a child is extremely impulsive, it might be best to wait until he or she is older than 12.
Did people and dinosaurs live at the same time? No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
So if humans lived at the same time as dinosaurs, but lived in different places, they would be fossilized in different places as well. Evolutionists believe that Dinosaurs died millions of years ago. But there is a great amount of evidence that dinosaurs lived only a few thousand years ago.
