Yep, living organisms have genetic diseases. It is because living things have genetic materials. And sometimes those genetic materials are copied incorrectly.

I dug a hole in my backyard looking for the earth's genetic material, but I couldn't find any. I couldn't find any earth cells neither. It appeared to me that the earth is made up of inert matter. I wonder if this experiment means the earth is not alive, and therefore can't make any kind of decision regarding humanity.
