The use of the word being in your context, the reader or listener will assume that there is more to the sentence. For example: "Creativity being the key to paradise, one must always find ways to be creative in their daily activities." other ways of using the word being in the same manner: "Being the only person at work who has the key to the door, I must get to work before everyone else" in this context, you can use "because" or "since".. Because I am the only person.. or Since I am the only person.

The use of “being” in this manner is similar to saying “because creativity is the key”. An example: Being the oldest in my family, it is my responsibility to take care of all my siblings. Because I am the oldest in my family, it is my responsibility to take care of all my siblings.

It is a participle. Creativity has many hypostasi, and one of them is the key to paradise, and being in this hypostasis it is (or does) something.
