Germs
The skin is the bodies first barrier to germs. It keeps out harmful germs and bacteria. As long as the germs don't penetrate the skin, they don't cause harm.
When they are first born
1.Your skin has three layers, and the first layer is meant to protect you from germs. 2.The hairs in your nose and (i know kinda of gross lol) helps fight back the germs. 3.Also, tears the come from your eyes help clean the eye from germs. 4.And your eyelashes help to.
By "germs" I have to assume you mean bacteria. And yes, it is supposed that the first organism was a prokaryotic cell, followed by eukaryotic cells such as plants.
The Plague started in 1340 in England on ships. Too many germs.
Medically cleaned of all germs
First off, they don't attack. Germs invade our body because its a nice warm, moist environment perfect for reproduction.
A barrier... in humans that would be your skin.
They didn't come to earth they evolved here
