Sure, if we all had amnesia.. but we don't so we remember and reference the past and dream of a (better?) future..

"To be ignorant of what occurred before you were born is to remain always a child"

Marcus Tullius Cicero, 1st century BCE

Your nervous system isn't pointlike, so all your senses are from the past. The 'now' you believe in is one you can never perceive.

And I thought this was a piece of irony such that it didn't even need quotes. Silly me.

The present is dead, the future is just a reheat of the past.

The is nothing new under the sun.
