Physicist: The 2nd law of thermodynamics states that in any closed system entropy will increase over time. That is, a living Human body has far less entropy than an equivalent amount of (most) inorganic matter, so how could living things have come from non-living things? Single-celled organisms never die of old age, they either die for environmental reasons or tiny murder. So, things don’t grow old and die due to entropy (strictly). In this case, there are a lot more ways to be dead than alive.
