The Genesis Cataclysm

Are there sufficient evidences to plausibly warrant positing a global Noahic Flood within the auspices of a specific Old-Earth biblical paradigm? If so, what are they? It is our firm conviction that God has allowed the passage of time to cover the blatant earthen signs of the Noahic Flood in such a way, and just enough, as to require earnest seekers of truth to use their eyes of faith and their vision of the kingdom metanarrative–along with their empirical sight and senses–to view and interpret the richness of the evidence. Prerequisites in this quest include a great respect for the authority of Holy Scripture, a pure heart with a simple desire for God's truth, and a relentless willingness to look for both «the forest and the trees» (viz., to see the multitudes of seemingly unrelated small scenes always in light of the big picture). The negation of any of these necessities will completely nullify the veracity of one's conclusions. However, we strongly aver that the totality of these necessities can bring the historical truth of the mystery of the Noahic Flood into a much, much greater clarity.
