Advanced technology gives us conclusive evidence of past events.

Explanation

For
Today technology is so advanced that we can reconstruct the past. For example, we know how Pompeii was destroyed. But now we have reconstructed the whole city. We know precisely how the people lived.

Against
It is an empty boast that advanced technology gives us conclusive evidence of past events. Let us take the case of King Tut. It has been C.T. scanned. What can it tell us how he died? If he was murdered then who murdered him and why ? C.T. scan might give some idea how he died. But it cannot give conclusive evidence.
