The ETs visiting Earth, particularly the ones known as Grays, are actually more inter dimensional than extraterrestrial, and they've evolved to higher levels of the universe beyond physical matter. If they need to come michael kors handbags clearance down here onto a physical planet like Earth to carry out work, then they make use of a physical body, or container to enable them to do that, just the same as our astronauts don a special space suit to enable them to travel in space. The Grays and other higher ETs aren't trapped inside their bodies as we tend to be down here.
