Keep in mind, man's abhorence and/or avoidance of the creation and the flood have little to do with his search for truth, but it has everything to do with the frightening implications that the lay of the land and the waters is a visible mark of the truth of God's wrath as well as mercy. Further, the idea of man getting better, which is the core of every evolutionary construct, is unachievable in a Biblical sense. That is too much for other religions and most men to bare, because it makes them responsible for their actions and their condition. Hence, the need for a Saviour, and the refusal to believe that He is necessary.
