Yep, the parables were. But New Testament scripture talks of Noah and the flood as an historical event.
All boils down to what we each choose to believe.
The current mount Ararat didn't even get its current name till the 12th century. That is when the Armenian Christians had the Bible translated into their own language. And since that is the only mountain of note in the area, it became "Ararat." If you read the scripture it says the "mountainS" of Ararat. It is in the mountains, not on a lone mountain on a plain.
