Fastest way to match longitutdes and latitudes, thousands of data points

My formula was the following, but will not run quickly so I will try your solution:

Sub Matching()

Dim rows1 As Long, rows2 As Long, i As Long, j As Long, result As Boolean

rows1 = Range("B" & Rows.Count).End(xlUp).Row

rows2 = Range("L" & Rows.Count).End(xlUp).Row


i = 1
j = 1

For i = 1 To rows1

For j = 1 To rows2



    If (Range("B" & i).Value = Range("L" & j).Value) And (Range("C" & i).Value = Range("M" & j).Value) Then
    result = True
    Range("I" & i).Value = result
    Range("S" & j).Value = result
   End If
 
Next j

Next i



End Sub

'Also, I was wondering if VLOOKUP would be a viable solution? I haven't used it and don't really know how, but I will try. I have also posted some example data, only the matching latitudes and longitudes should be copied into a separate sheet next to eachother.
