Biblical archaeology is all about finding out about things that happened a long, long time ago in history by digging up artifacts or things that people used or made thousands of years ago. These artifacts can be things like ancient buildings, pottery, tools, or even just little pieces of stone or metal.
This type of archaeology is especially interested in figuring out things that are connected to the Bible, which is a very old book that tells stories about people and events from a long, long time ago. So, archaeologists who work in this field often try to find out if the things mentioned in the Bible really existed, and if they did, what they might have looked like or how they might have been used.
To do this, they use a lot of different tools, including shovels, picks, and brushes to carefully dig up dirt and uncover the artifacts that they are looking for. They also use machines like radar to "look" beneath the ground without having to dig. Sometimes, they even use cameras and 3D imaging to create realistic pictures of what ancient buildings or objects might have looked like.
Overall, biblical archaeology is all about learning more about people and events from a really long time ago, especially ones that are mentioned in the Bible. It helps us understand more about the history of the world and the people who lived here a long, long time ago.
