Okay, so a log cabin is a type of house that is made out of wood logs. Imagine if you took really big sticks and stacked them on top of each other, making like a tower. That's kind of what a log cabin looks like, except with more logs and in a rectangular shape.
People used to build log cabins a long, long time ago because they were easy to make with the resources they had. They would cut down trees with axes and then use those logs to build their house. The corners of the logs were notched so they could fit together tightly and make a sturdy structure.
Log cabins were often built by pioneers who were exploring new places and needed somewhere to live. They were also popular in areas with lots of trees, like forests, because wood was easy to come by. Even today, you can still find log cabins in some parts of the world.
So, that's what a log cabin is. It's like a big, sturdy tower made out of wood logs. It's a little different from a regular house, but people have been living in them for a very long time!
