>>If you don’t believe Genesis, then you don’t believe God.<<
I’m curious, as a Christian, as to how you derive that requirement. Consider the gentiles that Jesus directly converted, who believed in Him and were saved. Does this mean they didn’t believe in God since they likely had never read Genesis?
I think that there is a difference between having read it and saying it is not true, and to have not read it.
The main point is that to denounce the Word of God is to call God a liar.
