Ok, if you mean that Now is the only time that exists, how do you reconcile that with the result of Relativity that no two observers will claim the same Now as the other?
If I'm in motion relative to you, the order of events I claim is simultaneous is different from yours, not just from my movement changing my perspective, as some seem to think... but also from the perspective itself being altered by the motion... such that you could say I'm moving through time at a shallower angle than a resting observer.
What would you say if I told you that as I am writing this, the moment when you read it and reply to it is a real event. It is somewhere off in the future from my perspective, but it definitely exists.
It is not coming into existence as you reach it, nor has the moment when I wrote this ceased to be at this later time.
We are looking at time in a very limited manner. Like looking into a large room through a keyhole. You can pan around and change what you can see through the opening, but the room doesn't stop existing where you aren't looking, does it?
