As I point out it doesn’t end there. Even if somehow some way humans just naturally couldn’t see them we have other senses we have other sensing technology we have inference. Mud and dust that show no footprints, radio site surveys that show no interference, radar, infrared, lidar…A lot of this stuff you can see for yourself
Heck how do they pass thru buildings to get in and out with density? Would we not all notice random doors and windows opening and closing? How many secure sites on earth where you need to badge in to a every room.
How hard to animals try to use camouflage? Maybe it’s just a natural state.
