"We cannot change our past but we can most certainly change our future." (Mum wisdom.)

The philosophy of Eternalism is the opposite of Presentism, stating that all moments of time, the past, present and future are real. It sees Time as a stable entity, present everywhere, and concludes that the future already exists, so we cannot change it.

Nothing exists except the present moment, as even the past or the future need the present moment to take shape. It seems shorter than a microsecond but encompasses all eternity.

Apart from this moment, one cannot be anywhere else.
