How if anything doesn't exist

I asked my self how does the universe start to exist and what the first of all event was. How about the other  far far away universe? Do we have allies out there? Once I realized that time is just one dimension of many. My understanding of time is that one thing happens after another. Physics tells that time and cause are just purely concept of our minds. We happen to live in a universe with physical law that allow conciousness to exist and travel along the dimensional "line". We are just seing one moment after the other. In fact, the history of our universe is just exist, it goes infinitely into the future and past. There would no first or last, it is actually like written in a book that has never be written. We are reading it but how we read it or where we start it  depend on who is reading it. There laid many mystery tales among the sky and the star that seem have no ending. 

And so, the real question is not why anything exists. But how if anything doesn't exist.

Clearly we are all just a stardust, we almost nothing but we made from a star stuff.

P.s. sometimes we gotta grateful just because we are a human-being. Isn't it nice to be a human?
