Sorry, this does not address a number of improbable events. Just some are
How did Noah round up and get so many "kinds" to the ark?
How did he ensure that they all survived?
How did he get them back to their places of origin?
How did all the creatures (only two of each kind) all survive after the flood in spite of dealing with the devastation of the prolonged and world wide flood? It is difficult enough to prevent species from going extinct when numbers fall under normal conditions.
How did all the species re-establish from just a pair of each kind (a question I also asked MrGordon)?
