Who was the first person to make a guitar in whole entire world?

There is no definitive answer to this question, as different cultures have different claims to the invention of the guitar. However, some of the earliest known guitars date back to the 15th century and were made in Spain. These early guitars were known as vihuelas and were similar to the modern-day classical guitar. The first guitars in the Americas were brought over by Spanish explorers in the 16th century and quickly became popular among both Native Americans and Europeans. Over the centuries, the guitar has evolved and changed, but it remains one of the most popular instruments in the world.
