Are those the real childhood clips on the opening theme of Men of a Certain Age?

Please settle an argument between me and my boyfriend. I say that the childhood clips on the opening theme of Men of a Certain Age (the kids they show when they post the names) are really the actors when they were young. My boyfriend says they cannot be. Who is right?|||Yes, they are. The were used to show a true side to the show. As the show is very honest and well realistic
