Almost Eternities is a term used to describe a very long period of time. It is often used to refer to a time that is almost eternal, but not quite. The term is derived from the word 'EON', which is a unit of geological time lasting for millions of years. EONS are often used to describe periods of time that are much longer than human lifespans. Therefore, when someone refers to Almost Eternities, they are referring to a period of time that is almost eternal, but not quite.
