A prophet is someone who is believed to have a direct line to a divine or spiritual source, and they deliver messages or predictions about the future based on this connection. A fortune teller, on the other hand, typically uses various methods such as tarot cards, palmistry, or crystal balls to make predictions about a person's future. These predictions are often based on the interpretation of symbols or signs. A futurist, however, is someone who uses data, trends, and analysis to make educated predictions about the future of society, technology, or other aspects of the world. They often use a scientific or analytical approach to forecast potential future scenarios. **

The concept of mathematics is not something that was "discovered" in the traditional sense, but rather it is a human creation that has evolved over time. Mathematics is a system of logic and rules that humans have developed to understand and describe the world around them.
