Why do germs exist and where did they originate from?
In: 1
Germs exist just like any other life exists. Why do you exist? Why does a fish exist? Why does a tree exist? They exist because they do.
They originated through evolution. They evolved from pervious single celled organisms. The early history of bacteria isn’t well documented having occurred billions of years ago and bacteria and their ancestors didn’t fossilise really well and they tended to look rather alike. There’s evidence of it, it’s just hard to study.
A lot of people tend to think any single celled organism is a germ or bacteria but that’s just not the case.
