It doesnt make sense to me… I know there was a past and there is a future although ‘now’ is fleeting. We measure time in days, weeks, months so how can it be an illusion? Oh and the belief that everything is happening now – what’s that about?
edit1: A lot of people are posting that time is not an illusion and where did I find that information from but there are articles where physicists state that it is. This is one:

I just wanted to know if someone could explain it clearly to me and I appreciate everyone who has tried to but it seems like a bit of a tricky and complicated subject. Thanks to all who have posted a comment.

How do you know there was a past? What if you simply sprung into being at this exact instant with all the “memories” of a past simply created along with you? How could you tell the difference?
But the real issue is that under Einstein’s well-tested views of space-time, everything that has happened, is happening and will happen MUST in some way be already firmly “baked into” the loaf that is space time. It’s a difficult concept to wrap one’s head around, but depending on your speed and direction of movement relative to other observers, you may see things happen in a different order than the other observers. In other words, you have different experiences of what has happened in the past (and exactly what is past v. what is present/future). You and the other observers would agree on the order that things happened, but not necessarily when they happened. It’s a bit heady for ELI5, but this video does a decent job laying it out – [Linky](https://www.youtube.com/watch?v=vrqmMoI0wks).
