When looking at history, you will find three types of evidence: the accepted conventional, the awkward and therefore ignored, and the new. Using proper scientific approaches, Rohl has challenged the existing conventional wisdom (to the usual howls of indignation from those too myopic to consider other views) and developed a radical new theory. There are clearly innumerable problems with the conventional wisdom, so Rohl has put his own ideas up - from there they will be tested themselves and either altered, confirmed or abandoned. This is certainly difficult material and is worth a steady reading, but has allowed so many apparently unevidenced or contradictory events to come into focus, all of which give a much clearer view of ancient history. Those who disagree must show where Rohl is wrong and develop their own ideas - the likes of Prof Kitchen merely deny it when their own theories are built on Egyptian sand. Essential reading, which also demonstrates what can be done with proper scientific methodology - in contrast to the kind of nonsense about lost civilisations put up by Hancock and others.
