Can someone give me a brief explanation to why Cameras were developed ?

Please make it short and simple.

I tried reading that but I don't understand

Cameras were developed because people have always wanted to have pictures of themselves, their homes, famous monuments, and scenery.

Cameras were developed to capture and preserve visual images. They allow us to document moments, communicate visually, and create memories. Cameras have evolved over time to become smaller, more portable, and higher in quality, providing a way for us to visually record and share our experiences.
