You would expect evolutionists to question whether Adam and Eve ever existed, but evangelical Christians? Well, many of them say it is impossible that we all came from the only Garden of Eden residents.
"That would be against all the genomic evidence that we've assembled over the last 20 years, so not likely at all," Dennis Venema, a biologist at Trinity Western University, told NPR.
Venema is a believer in evolution as well as being a Christian. He said it is clear that humans evolved from primates as a large population. He said scientists say the population has never been below 10,000, let alone just two.
Venema is not the only Christian who feels this way.
"Evolution makes it pretty clear that in nature, and in the moral experience of human beings, there never was any such paradise to be lost," said John Schneider, a former theology professor at Calvin College in Michigan. "So Christians, I think, have a challenge, have a job on their hands to reformulate some of their tradition about human beginnings."
However some Christians refuse to take up that challenge.
"From my viewpoint, a historical Adam and Eve is absolutely central to the truth claims of the Christian faith," said Fazale Rana, vice president of Reasons To Believe, an evangelical think tank that questions evolution.
Rana admits that small details of the Bible could be wrong, but not Adam and Eve -- that's too big.
"But if the parts of Scripture that you are claiming to be false, in effect, are responsible for creating the fundamental doctrines of the Christian faith, then you've got a problem," Rana said.
