Why do pigeons represent peace?

It was not until the beginning of the era that pigeons were regarded as a symbol of peace. The Christian Bible Genesis of the Old Testament records that after the ancient flood, Noah released a pigeon from the ark to find out whether the flood had subsided. God told the dove to take back the olive branch, indicating that the flood has subsided and there is still hope on earth. Noah knew that the flood had begun to recede and that peace was coming. After the flood receded, a valley full of green trees and a quiet path full of flowers appeared in front of everything in the world. Since then, people have used pigeons and olive branches to symbolize peace.
