I have a collection of 166 published statements relating to belief in historical Adam and Eve that I have categorized as yes, yes but not the first humans, maybe, or no, based on my interpretation of their statements.
Seventy-one theologians, pastors, and scientists expressed belief that either a literal or literary Genesis, New Testament references, and/or doctrinal necessity requires accepting an historical Adam and Eve. These are probably not candidates for acceptance of Genealogical Adam.
However, the following thirty theologians, pastors, and scientists have expressed belief in an historical Adam and Eve who were not the first humans. Those still living either are or could be amenable to accepting Genealogical Adam:
Denis Alexander, Kathryn Applegate, Gleason Archer, Craig L. Blomberg, Roy Clouser, C. John Collins, Gregg Davidson, Darrel Falk, Gary N. Fugle, Jon Garvey, Bruce L. Gordon, Terry M. Gray, Daniel M. Harrell, Carol A. Hill, Timothy Keller, Kenneth W. Kemp, Derek Kidner, Gavin Ortlund, Alvin Plantinga, Harry Lee Poe, John Polkinghorne, Peter RĆ¼st, Jeffrey Schloss, John Stott, Antoine Suarez, S. Joshua Swamidass, Carl W. Treleaven, John H. Walton, N. T. Wright, and Anthony Zimmerman.
The following 59 theologians, pastors, scientists, and others do not accept an historical Adam and Eve. Those still living could be candidates for possible future acceptance of Genealogical Adam:
Joel Edmund Anderson, Francisco Ayala, Karl Barth, Mike Beidler, John J. Bimson, Peter C. Bouteneff, Emil Brunner, Scott Buchanan, Ted Burge, Ron Cole-Turner, Richard G. Colling, Francis S. Collins, Simon Conway Morris, Greg Cootsona, Oliver Crisp, Conor Cunningham, Allan J. Day, Daryl P.Domning, James Dunn, Denis Edwards, Peter Enns, David Fergusson, Karl W. Giberson, John Goldingay, Morgan Guyton, Adam Hamilton, Daniel C. Harlow, Mark Harris, John F. Haught, Christopher M. Hays, Colin J. Humphreys, Luke J. Janssen, Luke Timothy Johnson, William G. Joseph, J. R. Daniel Kirk, Robert C. Kurka, Denis O. Lamoureux, Gregory J. Laughery, Jack Mahoney, Alister McGrath, James F. McGrath, Scot McKnight. J. Richard Middleton, Daniel L. Migliore, George L. Murphy, Thomas Jay Oord, Arthur Peacocke, Michael Roberts, John R. Schneider, Raymund Schwager, Paul H. Seely, Christopher Southgate, Kenton L. Sparks, John E. Toews, Dennis Venema, Edwin Walhout, Keith Ward, Patricia A. Williams, and Kurt Willems.
And here are six who were on the fence about an historical Adam at the time of their writing:
Gregory A. Boyd, Billy Graham, C. S. Lewis, Tremper Longman III, Ernest Lucas, and David L. Wilcox.
I am open to any additions or corrections (with references).
