I have had many discussions with Christians on this topic. Perhaps you have also.
Amazingly even some ‘old’ old friends who are Christians think it is ‘ok’ to believe in evolution. They do not see any problem or contradictions in saying that the first chapters of Genesis are not valid history even though the Bible records the events as being true history.
But, is it really ok to say the first 6 or so Chapters of Genesis are not true history and that God did not create the world and everything in it the way the Bible teaches?
Obviously there some serious theological problems that need to be addressed if a Christian accepts the theory of evolution and millions, billions, or whatever time span is currently proposed (since it keeps changing).
This short article (yesterday we had a long article to read so I tried to find a shorter one for today), succinctly addresses several of the fallacies that must be resolved if a Christian believes in evolution.
Whether you believe in evolution or not, this is a very good, timely, and short ‘must read’ article. HERE’S THE LINK.
