Science question are items falling?

When we drop something it falls to the floor or any thing or object they all fall to the ground.i have a theory are we sure ,could it not be that the earth is traveling upwards so when we let things go instead of them falling are we not going up with the earth
Answer
Would not that mean that if somebody did a parachute jump for example, the earth would have to expand by several hundred feet? multiply this by the number of people in the world doing this (or bungee jumping) and the earth would be expanding by a few miles a day. then when you convert this to distance expanded over several years. .this may lead you into another theory for the reason behind global warming, that we are now thousands of miles closer to the sun.
