My First Person Controller Falls through the terrain!

I have a first person controller w/ mouse look on the main camera and a flashlight that I made that has a spotlight. I also made a terrain and when the guy spawns, it always falls through the terrain a little bit. The flashlight always sinks through the terrain a little bit and it looks weird. Can someone help?

Have you added a character controller component? Also, if the mesh of the model touches the ground on the editor, it falls through the terrains… Try moving it up a little bit!
