Not all the dinosaurs were huge, indeed some were very small. They and their reptilian ancestors lived over a period of more than two hundred million years. The last dinosaurs became extinct around 65 million years ago.

It is physically impossible to know, or even estimate, the exact number of living reptiles there are in the world, but they are many records regarding the vast types (or number of species) of reptiles that inhabit Earth.

The word inhabit means to live in or occupy a place or environment. For example, as humans, we inhabit planet earth.
Reptiles do not typically inhabit extreme environments like the high altitudes of Mount Everest. The cold temperatures, lack of vegetation, and low oxygen levels make it unsuitable for most reptiles to survive. Most reptiles are found in warmer climates at lower altitudes.

The most recent one was the Cretaceous-Tertiary event, about 65 million years ago. Prior to it, reptiles were still the dominant species on earth. After it reptiles - especially the huge ones (dinosaurs) gave way to mammals as the dominant species. An event after which the distribution of earth's fauna changed dramatically.
The dinosaurs were reptiles and once roamed the earth.
