There isn't a single universally agreed upon name for everything that exists. Different philosophical and scientific perspectives offer different terms and concepts. Here are a few examples:

* The Universe: This is the most common term, encompassing all of space, time, matter, and energy.

* Reality: This refers to the state of things as they actually are, in contrast to dreams or illusions.

* Being: This philosophical concept encompasses everything that has existence, both physical and metaphysical.

* The Cosmos: This term often emphasizes the interconnectedness and order within the universe.

* Existence: This is the most general term, simply meaning the state of being real or present.

Ultimately, the choice of name depends on the context and the specific perspective you are considering.
