How do you find anything on Google Earth?

If you have an address, city name, or just latitude/longitude coordinates then you can fly to that location in Google Earth. Just enter the address or coordinates into the Search/Fly-to text box in the sidebar.

You could also do advanced queries such as "hotels near Paris" to display hotels near the city of Paris. The same queries that work in Google Maps work in Google Earth.

If don't have a particular location in mind, but you want to browse many of the interesting finds in Google Earth by category then there are numerous published lists available. For example, check out the Google Earth Community (GEC) forums.
