Japanese has two verbs to express the English phrase there is, there are. The verb ある is used for inanimate objects, and いる for living beings. The polite forms of these verbs are あります and います respectively. You will learn how to conjugate verbs later. The verbs ある and いる are used together with the particle が to express there is, there are.
You can also use the verbs together with ni to indicate the location of things, without it being translated to there is, there are.
Note that even though you can say ここです to indicate that you are here, you cannot say 王の車です to indicate that you are inside the king's car, since this sentence means It is the king's car. You also cannot use です in combination with に, so 王の車にです is ungrammatical.
