Astrophysics/a living universe?

Question
I've been thinking about the universe's expansion lately and I
realized that growth is one of the main things that separates
living things from nonliving things. So, if the universe is
growing does that mean that it is alive?

Answer
Living things grow by a specific process that is based on multiplication of living cells - which contain DNA, nuclei etc. The universe by contrast has no living cells, and whatever growth has no parallel whatsoever to an organic entity. "Growth" is a poor word to use for cosmic expansion since the material components themselves (e.g. galaxy clusters) are not multiplying. (Stars are being formed, true, but this isn't the same thing)

Further, there are other characteristic attributes of living things besides growth, which include reproduction, nutrition, metabolism...etc. none of which remotely applies to the cosmos.
