I assume you mean "Why does Finland exist?," or, "How did Finland form?"
Finland was formed by the Treaty of Versailes, which ended World War One.
EDIT: No, Finland wasn't formed by the Treaty of Versailles. Finland is an older nation which has been under the Swedish empire and later the Russian empire.
