“A skeptic can never gather enough evidence and a believer does not need any!”

Just because you can not see microorganisms does not mean they do no exist. We know this to be a fact. We can use instruments such as a microscope to see their existence. There is so much that extends beyond the limits of out 5 senses.

Even though we can not always see it, smell it, hear it, feel it or even know what we are speaking to, does not mean it does not exist.
