If we are standing on Earth which is rotating about its axis at 1000 mph, and the Moon is elliptically orbiting around the Earth at 2000 mph while always facing Earth (Tidal Locking), and the Earth is elliptically orbiting the Sun at 66616 mph, and the Sun is orbiting the center of our Milky Way Galaxy at 500,000 mph, and the Milky Way Galaxy is moving at 1,340,000 mph with respect to extragalactic frames of reference, why do we not feel any acceleration? Round Earthers often cite the example of it being possible to play a game of catch on a moving vehicle because the relative speed of the two people playing catch and the ball remains constant with the speed and direction of the moving vehicle. However, if during the game of catch the moving vehicle accelerates, the ball should hit the back of the car, and if the car decelerates, the ball should hit the front of the car. We can experience the acceleration and deceleration of a 15 mph car crash, so why do we not feel any acceleration/deceleration of the cosmic bodies we supposedly stand on?

There is no acceleration. The speed earth moves is constant. It only changes depending of your perspective but since there isn't a single object in the universe that is not moving relative to something else, there is no way to calculate the real speed. These numbers you said are just approximations based on our perspective on earth.
