Obviously the works of God! Wondrous are His ways!! Hallelujah!!!!!!As a biologist who studied fish...how do they explain the survival of saltwater/freshwater fish after the flood? Depending on how you look at it, changes in salinity brought on by 40 days/nights of rain would have caused a lot of problems for the fish of either group. And do they even mention how all the land plants survived? Again, a flood that covered everything would have changed the soil characteristics of all the land on earth...not many plants could survive that kind of change.
