Obviously you don't have the slightest clue what you're talking about.Trees can be submerged underwater for a period of time without losing their leaves. The water subsided revealing the olive tree with its leaves still intact.
Scientists uncover a 60,000-year-old forest underwater and think its preserved trees https://www.cnn.com/2020/04/07/us/ancient-underwater-forest-alabama-scn-trnd/index.html ? I give you an "F" again for failing your science class. Lol I can't discuss with you further because you failed in the comprehension department. Lol Bye.
As a retired plant physiologist and orchardist I can assure you that an olive tree cannot survive being completely submerged for weeks as you hypothesize.
If you believe otherwise then present your scientific evidence and scientific publications to support your claims. But either way, it still doesn't change the fact that the KJV clearly says that the flood depth was only 15 cubits and drained away like every other flood. And it's your choice if you don't believe what the bible actually says and just make up your own silly fantasies about the ocean levels magically rising at the rate of 150 mm per minute for 40 days and covering Mt Everest with an extra 4.5 billion cubic kilometres which then magically disappeared.
And none of that changes the fact that Gen 4 says that Jabal & Jubal and their families were obviously not drowned in that particular flood with most of Noah's family given that the bible says that they are the fathers of ALL musicians and tent dwellers and herders.
And it's your choice if you don't believe what the bible actually says.
