I remember this movie I saw when I was about 6 which was in 2005. The movie itself though looked like it was probably filmed sometime in the 90s. It was about a caveman that was taken in by a family and all I remember is at the end he’s somehow back in the time he’s supposed to be in. The main cast was made up of primarily white people and it might have had a few funny parts but I don’t think it was a comedy. It was also in color and in English and I don’t think it was a TV movie.
Encino Man (1992)?

The Jungle Book? Jason Scott Leehttp://youtu.be/uBAku3Cwsgk
Sorry. I am not sure what I attached but I tried attaching the trailer.
Also think. Tarzan the ape man with Christopher Lambert.
This is a reach, but I’m going to guess “Greystoke: The Legend of Tarzan.” He’s not a caveman, but a boy raised by apes. It has some pretty funny moments.

Also. Walk like a Man, with Howie Mandell.
Its Harry and the Hendersons
