Time is relative to the observers point of view. To say that's a fact that there is only one reality...is strictly your point of view, and there may be billions like you.........how many people in the world?....then there are at least that many universes....our worlds may seem alike..but no more than were alike. your past exists now as you think of it, your future exists now as you think of it...the moment point is now as you think of it....everything is relative to the observers point of view..who's to say the color blue is the same for you and me...we may agree as a basis point on an what we perceive as an object or event but that's all we can do...and what we agreed on is how the sciences started....outside of those "sciences" time only has meaning when we think of our own individual perception of it..... your basically "all" right!
