It depends on the way you look at it. I like to quote Juian Barbour, a British physicist, author, and major proponent of the idea of timeless physics:
"The only evidence you have of last week is your memory. But memory comes from a stable structure of neurons in your brain now. The only evidence we have of the Earth's past is rocks and fossils. But these are just stable structures in the form of an arrangement of minerals we examine in the present. The point is, all we have are these records and you only have them in this Now."
