Okay kiddo, let me explain who James Hutton was.
James Hutton was a really smart man who lived a long time ago in Scotland. He loved studying rocks and the earth, and he wanted to understand how the earth was made.
He looked at lots of rocks and found that they were layers and layers of different types, some hard and some soft. He also found that the rocks were shaped by things called erosion and weathering, which meant that rain and wind could slowly change the shape of rocks over a long time.
James Hutton also believed that the earth was really old, like way older than anyone had thought before. He thought that the earth was millions of years old, and that it had changed a lot over that time. This idea was really different from what people believed at the time, but it turned out he was right.
His ideas helped scientists learn more about the earth and how it was made, and they still use his ideas today to understand things like earthquakes and volcanoes. So, James Hutton was a really important scientist and helped us learn a lot about our planet!
