I still don't really see how it's relevant. Words are pronounced and even largely mean the same thing in C, C# and Java as well. Syntax nearly identical, punctuation nearly identical, meaning nearly identical. Indonesian and Latin share the same alphabet in present time but they sure didn't evolve that way. The spelling and script were adopted long after the language evolved over top of its own script systems.
C# and Java are derived from C. There are clear evolutionary relationships. Only an imbecile would try to claim otherwise. Give it up dude.
