An advanced technology attained with easy techniques has been used in the past times

Excerpt from Mr. Adnan Oktar's Live Interview on A9 TV dated July 25th, 2011

MS.BETUL: Master, Sabah Daily [Turkish daily paper] made a news article about a subject matter that you have explained years ago and given place in your books. The article reads.. In the news article about this matter, they have stated that in the drawings dating back thousands of years, technology products like helicopters, airplanes and tanks were noted and that processed giant stone blocks had been easily moved thousands of years ago, that there had been drawings similar to electric bulbs and generators on the walls of caves, that propeller planes had been seen in the ancient drawings -let me show you the pictures as well- .. and stated that all these discoveries had dazzled the scientific world and left the scientists at loss in coming up with an explanation. 

ADNAN OKTAR: Yes, there are many other wondrous aspects that they do not know. I mean at those times, systems that give results much more easier than today's technology.  For instance televisions were used but with a much more easier technique. I mean it was not with such a complex technique. For instance they have made atomic bombs but with a much more easier technique. Hazrat Khidr (pbuh) had used atomic bomb and Allah made angels use them as well. They have a simple system, very easy. When a substance gets into a reaction with another substance, we understand that they have the same effect of the atomic bomb. For instance when the messengers came to the people of Lot they said; "none of you should look back". There with an easy system Allah made something instrumental and an explosion with the exact same effect of an atomic bomb occurred.

That is also something Hazrat Khidr (pbuh) does. I mean people are making scientific inventions; for instance [Nikola] Tesla, this and that.. and they are inventing many things but they do so with complicated systems. And there are also very easier systems. For instance at the time of the Prophet Solomon (pbuh) television existed but it was established with a very easy system. It had a very simple system. For instance atomic bombs have been used, they have been used many times. We see this in the Qur'an. We understand that from the state of the cities as well, but these are established very easily. They are building planes but they do so with a very simple and easy system. For instance the weight of a substance could be reduced and they do so with a very simple system. But these have not yet been founded. Some of them are only estimated, some of them are inquired, and there are some that we see.
