To what degree? It's hard to answer your question unless you're a little more specific.
Are you asking about the abiogenesis of cellular life, or are you simply asking what physically makes a cell alive? Both have very different answers, although perhaps each are equally complex. As for creating new life from scratch, unless you're planning on dying soon, I imagine it will be a scientific accomplishment that you'll be seeing within your lifetime. It's already possible to create a virus from scratch (although whether a virus classifies as life is debatable), and recently some geneticists were able to insert the code of one bacterium into another, turning the second bacterium into a clone. This is actually pretty amazing when you think about it, because it's, albeit on a smaller level, the equivalent of my putting all of my DNA into you and your body turning into an exact copy of me. To my knowledge, there's some very promising programs working on actually piecing together an entirely new cell from scratch.
