Because the people who decided to name them bits decided that 8 bits makes up a byte. It is just like asking why is a knife called a knife no real reason.
8 bits grouped together is called a byte. A byte is a unit of digital information in computing and telecommunications that typically consists of eight bits. Bytes are often used to represent a character such as a letter, number, or symbol in a computer's memory. The size of a byte can vary depending on the computer architecture, but it is typically 8 bits on most modern systems.
