According to the Universal Law of Gravitation, every object attracts every other object, including you and Mars. However, the reason why you cannot feel the force of attraction between you and Mars is that this gravitational force is extremely small due to the vast distance between Earth and Mars. The gravitational attraction decreases with the square of the distance separating the objects, so even though Mars has mass, the force it exerts on a person on Earth is minuscule and imperceptible to human senses.
