Question

why atlantic ocean is the busiest ocean in the world

Answer 1

It's because the world's leading countries I.e. European and American countries are situated there...

Answer 2

Because it is between Europe and North America, which, historically, have always been closely linked by mutual trade. From the mid Nineteenth to the mid twentieth century( roughly 1850 to 1950) the largest, and fastest, passenger ships were always the ones on the North Atlantic, symbolic of the importance placed on trade between those two regions of the world. Even today, when passenger traffic goes by plane, rather than ship, more people fly over the Atlantic than over any other ocean in the world, while the cargo trade between the “new world” and the “old”(North America and Europe) is still of vital importance to both those parts of the world, a fact that is still true, even though trans Pacific trade, between North America and Asia, is increasing all the time.
