Verified step by step guidance

1. Step 1: Understand the historical context of the microscope's invention in 1666, which was a pivotal moment in science.
2. Step 2: Recognize that the microscope allowed scientists to observe microorganisms, which were previously invisible to the naked eye.
3. Step 3: Note that this observation revolutionized biology by opening up a new field of study focused on microorganisms and their roles in health and disease.
4. Step 4: Clarify that the invention did not immediately lead to the discovery of antibiotics or vaccines, as these developments occurred much later.
5. Step 5: Understand that the microscope is distinct from telescopes, which are used for astronomical observations, so it did not replace telescopes.
