Newton,s thinking was poor

Hello steemians ! Do you know ? what is gravitational force ? Why does everything comesto the earth in the gravitational field?Why does everything in the gravitational field not attract earth to itself ? Newton answered these questions. He told that earth having greater mass than that of everything in the gravitational field attracts to itself due to the gravitational force . when object object in the gravitational field has smaller mass than that of earth , then its force must be smaller , so object does not go upwards ; its force must be greater than mass of earth but Newton failed to answer this question : Who has kept the force of object smaller than that of earth ? Think upon it and please answer me.
