What is reality?

Fuck if I know.
After much time spent thinking and serving food:
Here it goes. So life holds no truth, because all things considered true are based on assumptions and best guesses. However, we all believe that these things are facts, truths. We base our reality on a set of assumptions. What does that mean? Simple reality is a myth, we assume what we consider to be reality is reality because it is all we think we know. Of course we do not actually know, we just think. The thing is my mind is to "complex" to accept that these things that are told to me in the form of "facts" hold any truth at all. However I am also to smart to reject commonly held beliefs, usually. Some of them hold some merit and are definitely the best possible explanation thus far. Yet I consider my self open minded enough to realize just because I believe something is the best reason does not mean a better reason will not come along. So while I say I know and explain things like they are facts, I believe what I am saying is simply the best possible explanation in most cases. Sometimes though I will reject one of these "facts" completely because it lacks the support I need to believe it, or the support is constructed from things that are not known as "facts." So what is reality? Fuck if I know.
