We have since learned that much can be discovered usig only natural means, but certainly not everything that we question has been answered. There is still plenty of room for faith even if we let down the barriers we think God told us not to cross.
Is this more room for faith, or more room for future research? If we pick faith, the research may never get done and we may be left with only fantasy, never gaining the knowledge that might have been ours.
Why not simply say "We don't know." when we don't know?
