On Brownsea Island in Great Britain.
Boy Scouts were founded first.
The Boy Scouts were started before the Girls Scouts and most of the "lore" such as signs was already well developed even in the first handbooks so it would have to be that the Boy Scout's sign came before the Girl Scout's.

Typically, boys join Cub Scouts when they are in first grade.
Girl Scouts back in the early 1920's.
When first starting Girl Guides/Girl Scouts in America in 1912, Juliette Gordon Low called the first troops American Girl Guides. A year later, the name was changed to Girl Scouts and, in 1915, the organization was incorporated as Girl Scouts, Inc.
First grade.
Girls were allowed into boy scouting in a program called Venturing. Girls were first admitted in 1976 to the Venture Scouts!
The first record of any Girl Scouts selling cookies was that of the Mistletoe Troop in Muskogee, Oklahoma, which baked cookies and sold them as a service project in December of 1917. Through the 1930's, Girl Scouts made the cookies at home.
