Copy cells from Sheet2, paste to next blank row in Sheet1

[marreco]

Hi.
the code below, demand data "Sheet1" with discretion in "Sheet2"
to find it overrides the value of "Sheet2" and put in "Sheet1"

Option Explicit

Sub Macro1()

    Dim rngCell As Range
    Dim lngMatchRowNum As Long
    Application.ScreenUpdating = False
    With Sheets("Sheet1")
        For Each rngCell In .Range("A2", .Range("A" & Rows.Count).End(xlUp))
            If (IsError(Evaluate("VLOOKUP(" & Sheets("Sheet1").Range(rngCell.Address(False, False)) & ",Sheet2!A:A,1,FALSE)"))) = False Then
                lngMatchRowNum = Evaluate("MATCH(" & Sheets("Sheet1").Range(rngCell.Address(False, False)) & ",Sheet2!A:A,0)")
                .Range("B" & rngCell.Row & ":F" & rngCell.Row).Value = Sheets("Sheet2").Range("B" & lngMatchRowNum & ":F" & lngMatchRowNum).Value
            End If
        Next rngCell
    End With
    Application.ScreenUpdating = True
    MsgBox "Todos os registros aplicáveis já foram atualizados."
 
End Sub

Now what I need is:
If the value of "Sheet2" not found in "Sheet2" so that the value
the "Sheet2" is inderido the next empty line (below) of "Sheet1"
