its because there was no way to see them
Not until the mid-to-late 1800s
Microscopes with sufficient magnification and resolution did not exist prior to the mid-1600s, making it impossible to observe cells. Additionally, the concept of cells as the basic unit of life was not established until the mid-19th century by scientists like Robert Hooke and Matthias Schleiden.
Cells are very small and can only be seen with a microscope, which was not invented until the late 1500s. Additionally, the concept of cells as the basic unit of life was proposed by Robert Hooke in the 17th century, leading to the discovery and study of cells as the building blocks of all living organisms.
The lack of microscopes with sufficient magnification capabilities before the 1600s prevented scientists from observing cells. It wasn't until the development of the compound microscope in the 17th century that cells could be visualized.

Scientists can study the structure and use it to find vaccines and cures for the bad bacterial cells and find the advantages for the good bacterial cells. You wouldn't want to test it on rats until you completely studied it.
