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.
Originally Answered: Did humans exist at the time of dinosaurs? This is really two questions. First, if youâre referring to the Mesozoic period, during which we recognize as dinosaurs such animals as Coelophysis, Brachiosaurus, Allosaurus, Deinonychus, Triceratops, and Tyrannosaurus, then no, humans did not exist then. There is nothing in the fossil record to indicate the presence of humans.
