"Reality" requires an element of faith to describe in order to prevent an inescapable philosophical feedback loop of self-reference. Reality exists - existence is reality.
The alternate is the view that reality is illusory. I don't fully grasp the concept, considering a very real fist landing a punch on my very real nose really hurts. So if you view this existence as a dream, I have no answer that will satisfy you.
To my way of understanding, reality is, it exists, we are in it. Regardless of how any of us explains it, or views it, or sees it, or interprets it...it is, what I call the IS. The universe and stars and galaxies and black holes exist, they are part of the IS, they are what IS. We are stardust.
15 thousand years ago human tribes pretty well viewed reality in the same or very similar manner...evidenced across continents with painted caves and rock shelters.
When humans became agrarian and began building fortified cities, we created delineating lines between tribes, and began focusing our myths into culturally specific and culturally meaningful dialogues, and with the development of writing put these teachings into script.
What is, simply is. How we perceive what is, is where humanity has long gotten complicated.
