I have been reading his books/articles since 2008.Most of "his"work was about how evolution is not true.
Then suddenly he turned into a person who is focused on why Israel has the right to be a state and that stuff.He also wrote lots about the Holocaust.
Many so called scientific articles are stolen.A simple copy paste in google will reveal the real authors of his works.
He is also pushing the idea of how everything is an illusion because he says matter is 99.999% empty and therefore only God exists everything else is just an illusion ,your soul according to him just sees images shown to it by God.His actually mixing God and a philosophical idea called Solipsism.
A rational person knows that the world is not an illusion ,it was created by God ,if it was an illusion he would have said so in his books God is not a deceiver.No prophet has ever said the world is an illusion.It's is a temporary world ,but not an illusion.
Harun Yahya has clearly gained the attention of Freemasons ,this man is not insane ,he is smart ,but he sold himself for money and beautiful women ( you will find him dancing with half naked women on youtube)
