John Mackay is an international speaker and is the Australian Director of Creation Research. He has been lecturing on the subject of origins and doing field research worldwide for the last 30 years.

In March 2005 John debated the UK’s leading theistic evolutionist, Dr John Polkinghorne in a lively clash, hosted by popular BBC commentator Roger Phillips. The entire debate was professionally filmed and adds to the long list of John’s debates against leading evolutionists. During 2004, John was asked to debate 3 New Zealand professors at once. His opposition included Dr David Penny who had just been awarded NZ’s highest science prize in genetics. In the preceding 4 years, John debated such notable opponents as Cambridge geologist Dr Trevor Emmet at the Mumford Lecture Theatre Cambridge, Geology Professor Dr Tim Astin at Reading University and Harvard University Professor Chris Di Carlos at Guelph University, Canada. During January 1999 he was pitted against Dr Eugenie Scott, head of the National Center for Science in the USA.
