The art we see today hasn’t always been the way of art. Through time, art has evolved in various ways. Nobody for sure knows how many forms of art there have been overtime, but it is a lot. 
An example of a type of art you may not have heard of is aboriginal art. Aboriginal art was created as far back as between 60,000 and 80,000 years ago and was originally created in Australia. 
Aboriginal art is Australian art that tells a story. There are multiple types of aboriginal art. For example, there is X-Ray, which shows the internal organs of an animal. Australians painted these usually to attract other animals of which the Australians would kill to expand their food supply. 
There is no written language for Australian Aboriginal People so in order to convey their important cultural stories through the generations, it is portrayed by symbols/icons through their artwork. There are many symbols to represent objects, people, animals, etc. Also certain colors in Aboriginal Art can represent certain things. For example, red can mean fire, passion, importance, or danger and blue can mean calmness, peace, responsibility, or strength. 
Another form of art used was Aztec Art. The Aztec Empire, centred at the capital of Tenochtitlan, dominated most of Mesoamerica in the 15th and 16th centuries CE. With military conquest and trade expansion the art of the Aztecs also spread, helping the Aztecs achieve a cultural and political hegemony over their subjects and creating for posterity a tangible record of the artistic imagination and great talent of the artists from this last great Mesoamerican civilization.
Art has always been an interesting subject in my opinion. It is diverse and very important to society today and it’s change is very significant.
