Here's why:
* Size: Most cells are microscopic, meaning they are far too small to be seen without magnification.
* Limited Technology: Before the invention of the microscope, humans lacked the technology to see things at such a small scale.
* Focus on the Macroscopic: Early scientific inquiry was primarily focused on observing and understanding the world around them, which was largely composed of macroscopic objects.
The invention of the microscope revolutionized biology by allowing scientists to see the previously invisible world of cells, leading to the development of cell theory and a fundamental understanding of life.
