The first reason why it can't exist is that it may just be made up by people out of faith. Because every country has its own beliefs, like our country is Pangu, so there is heaven and earth, and then Nuwa made people. Then in the belief of western countries, it was Noah's ark that saved the living things, so all this can't be taken seriously. After all, this is just a fairy tale. No one saw it with their own eyes, but it was handed down orally.
The second reason why it can't exist is that the site of Noah's ark can't be found. Because the Bible records that there are many animals in Noah's ark, and they are all in pairs, so as to ensure that everything in the world can survive and reproduce after the flood. If it is such a huge project, some sites will be left behind, and it is impossible to disappear quietly. But some people say that there may be sites, but they are all consumed because of too long time.
The third reason why it is impossible is that the project of Noah's Ark is huge. This last point can actually be compared with a "Noah's Ark" now. After all, many people are dubious about the existence of Noah's ark. A Dutchman built one himself because he believed in the existence of the ark too much. Although it is really a miracle, it can't prove that Noah's Ark ever existed, so now all this belongs to the unknown. I hope someone can clear the fog in front of Noah's ark in the future.
