You can literally throw rocks to earth at 1/36 the cost to leave earth. The rocks would then naturally fall to earth.

Missiles have to be launched and require much more acceleration to reach the moon and leave earths gravity.

To put it into perspective, imagine the moon can catapult 5000 massive rocks at earth every day. Earth can’t make that many missiles fast enough
