"Obviously, the past does not exist; it is a collection of mere memories, impressions in the mind. But the future also does not exist; it is a collection of ideas about what should or might happen"

It's been proved beyond reasonable doubt that time is as real as space and what is an illusion is the flow of time. There is no "present" moment. Every moment and place exists in time-space with different versions of you thinking they are in the present. So it's exactly the opposite.

You could say that taken one of those points in time and named it "present" you can say that the past and future do not existent within that moment. But because of the relativity of simultaneity you now also have to pick an arbitrary frame of reference to define "preset".
