Why can’t aliens be tiny….requiring tiny ships?
If they are organic beings, their size cannot be random. Their size is basically defined by the size of their planet and by evolutionary forces, which
defines a very specific range of sizes.
The evolutionary route that any species takes can only provide organs of a certain size and functionality to support a given body size. Your aliens
cannot be shorter than 53.4 cm if you want them to be anthropomorphic, that is, human-like.
If you still want them to be really small and intelligent, then you must know that their home planet must still keep a dense enough atmosphere to keep
liquid water on the planet, plus a substantial magnetic field to protect them from radiation. Additionally, the planet has to be big enough for the
gravity to hold onto an atmosphere. Being aneorobic is useless because "anaerobic" means living or occurring in the absence of free oxygen, which
still means you need an atmosphere. Given those conditions, the shortest beings you can expect will be just 48.6 cm. They would collapse if they ever
try to step a foot on your planet. That's why fairies cannot exist: they all would die of aortic valve stenosis.
You can figure out creative solutions, such as liquid beings, or gelatinous, or insect-like, or ethereal beings made of gas. But then their
intelligence must be swarm-based, collective, and in that case the design of the UFOs would not resemble anything you see.
In any case, they would die as soon as they set foot on this planet.
