Humans, plants and animals are related because in the beginning of a world of experiences they were interchangeable.
”That is to say that everything in the natural world has a relationship with every other thing and the total set of relationships makes up the world as we experience it.”(Vine Deloria)
And time as an experience in this sense, does not pass. It is an aspect of reality. Percieved as passed it is a set of different times in a constant reality of absolute time. Because time has to be part of something. This is what gives our senses the ability to take part in the relations experience have of everything simultaneusly.
It is a constant phenomenological reality we relate to as all time, or sometimes just as eternity.
