In response to:
"Why can't God write in symbolic ways? (You seem to be boxing Him in by saying that either he is lying or he meant the Genesis account to be simple historical fact.)"
God can and does write in symbolic ways in Scripture. He also writes, through inspired authors, in literal ways. How did Jesus and the New Testament writers treat the Genesis account, as symbolic or literal? If Jesus didn't know how to interpret Genesis, then, confessedly, neither do I (I am not claiming perfect interpretation ability for myself). However, if Jesus claimed the Genesis narrative was true, and refers to its historic authenticity (not as symbolic), you can accept His words or reject them, just as people of His earthly days did.
Do you have scriptural examples of the views of Jesus on the historical accuracy of the Genesis account? (sincere question, not trying to be argumentative)
