Does One Equal Infinite?

What do the big bang theory, conventional religion, and the human body have in common? They all started with the notion of one. One large piece of exploding matter, one infallible entity, and one drop of semen. The question you many have is so what? So what if they all have a common singular beginning? Is it that the painting reflects the artist? So that we come from one drop of semen, because nature began in one moment with one source, and is that source the one infinite being? Then again if the painting does reflect the painter and the painter is ultimately infinite, should his or her work not also be infinite? In other words, is the fact that we are finite evidence that our source is also finite, or that our source can’t be infinite? Another question: how do we know whether we are finite or not? True our body needs to eat but do we as an existing atomic structure need to eat? Once we die our body is still there, albeit decomposing, but our body needs neither sleep nor food, shelter nor family, sex nor air! Maybe we, in our entirety, reflect in some ways the infinite. Or when we die we return to the one that we began as, one matter, dirt. Is it that the same experiences that makes us feel finite, life and consciousness, also prevent us from truly experiencing the one infinite that is at the heart of everything? Is the unifying factor that we all come from the same source and it is our consciousness, our physical existence, that precludes the obvious? What if we are aware that this oneness is the infinite source and if so is it interchangeable with the term infinite?
