well if people don't want to believe they are cause of human and machine error...
I could suggest the following crazy ideas....
1. space bugs, the aliens in underground bases accidently let a fly type bug from their homeplanet get on their ship and now its here, and it's the
cause of sars.
2. They are actually bullets from a rail gun.
3. Super evovled bugs flying at sub light speeds
4. super small micro alien space crafts, they like to fly around
5. evil spirits
6. Some sort of crazy animal like those ones in the FF movie
