Something like this function should work...

Private Function SheetExists(sname) As Boolean
On Error Resume Next
IsError ActiveWorkbook.Sheets(sname)
SheetExists = Err.Number = 0
End Function

Just call it from your own code (macro, function, event procedure, etc.)
like this...

MsgBox SheetExists("AAA")

The function returns True if the sheet exists and False if it doesn't exist.
