Okay kiddo, let me explain it to you in a simple way. Azerbaijanis are an ethnic group of people living in the country of Azerbaijan which is located in the South Caucasus region.
A long time ago, people started living in different parts of the world and they formed their own societies with their own cultures and languages. This is what we call an ethnic group. Azerbaijanis are also an ethnic group, but they didn't just appear out of nowhere.
Thousands of years ago, there were people who lived in this region of the world and they had their own way of life. They spoke a language called Old Azerbaijani, which is different from the language Azerbaijanis speak today, but it was still a part of their heritage. Over time, people from other parts of the world came to this region and brought their own customs and languages.
As more people came to this region, the Old Azerbaijani language was influenced and changed by the new languages that were spoken, which eventually led to the development of modern Azerbaijani language that Azerbaijanis speak today.
So, basically, Azerbaijanis have a long and rich history that goes back thousands of years. They have their own unique culture, traditions and values that have evolved over time, and they continue to celebrate and honor their heritage to this day.
