Been on a few religious and political forums, excluding Fundie nonsense, so far the following has pretty much shut down the non believers in their tracks.
Maybe mentioned here before, but thought I'd toss it out.
Works good to silence the non believers at the water cooler at work too (when this subject comes up).
....................
1. I as a mere mortal do not know how long one of God's days is/was.
2.The Bible was written to be timeless in application and understanding- to a wide range of inellects and various levels of technical knowledge- some of it is symbolic.
If not symbolic then people would get hung up on a minor issue and not continue the travel through the pages.
3. Adam and Eve were simply the first of God's creations to have souls.
All of the above allows for a mixture of creation and evolution, so there is no argument.
Those that don't want to believe in God or Christ need find another scapegoat
