In the early days, there were considered to be two kingdoms, plants and animals. It was in 1969 that Cornell's Robert Whittaker came up with the idea that all living things could be divided into five major groups: the Monera, Protista, Plantae, Fungi, and Animalia Kingdoms. More recently, based on cladistic anaylsis, biologists usually consider there to be 3 major domains: Bacteria, Archaea and Eukarya.

It's not entirely that accurate. But here's the intro: on the earth, you might have noticed that there are living organisms and non-living organisms. Within the living organisms, they share common traits and characteristics based on factors like their appearance (different fish like salmon and bass; humans and chimpanzees), common ancestry (insects come from a common descendant), etc. Different scientists go by different procedures, but the main point is that these diverse organisms can be classified according to common traits. The most modern form of this classification lies in DNA, which developed in the middle to late 20th century, first publicized by Watson and Crick's model of the double helix. Based on shared common DNA, which now scientists have determined implies common ancestry, taxonomists classify various organisms based on kingdoms. All animals of a certain kingdom share very similar traits, and usually come from a common ancestor. For example, the horse and other hoofed animals both come from a common ancestor which passed on its hoofed trait to these animals.
Now scientists have classified it based on 2 Domain: the living organisms, which divide into 5 kingdoms, and the other Domain of a class of ancient bacteria.
Hope that made sense!

Sure.

"All living things fall into five kingdoms." That's all there is to it.
