The non avian dinosaurs became extinct 65.5 million years ago. The earliest sirenians, (the order that includes manatees), didn't evolve until about 50 million years ago, 15 million years after the extinction of the non avian dinosaurs. However, scientists consider birds a group of dinosaurs, and, because birds still exist today, manatees do coexist with avian dinosaurs.
Did Dinosaurs live at the same time as people?
No. The "Age of the Dinosaurs" lasted for about 150 million years. In that long period of time, many different types of dinosaurs arose, flourished, and then went extinct. When a group of dinosaurs went extinct they would just be replaced with another group.

Dinosaurs existed because a group of archosaurs evolved to have legs directly underneath the body, a defining trait of the dinosaurs. They may have become so diverse because at the end of the Triassic, a mass extinction opened up many niches, and dinosaurs were able to evolve quickly enough to fill them. Modern birds later evolved from dinosaurs.
