In nature, the formation of interesting systems through the aggregation of small structures is frequently observed and leads to the emergence of complex systems, known as emergence. Emergent properties are unexpected characteristics that appear in the whole system, beyond the individual behaviors of its components. Examples at the micro level include cells coming together to form organs or neurons collectively giving rise to consciousness. At the macro level, interactions between plants and animals, species diversity, energy flow, and matter cycling lead to emergent properties. These properties, independent of the behaviors of individual organisms, are observed in the entire ecosystem, making it more complex and dynamic.

I recommend watching this video related to the topic. You will find it quite fascinating.

Beyond this, my thoughts on the definition of life are as follows. The first step towards life is the ability of an entity to adapt to changes in its environment. At the most basic level, ions can be considered; they gain or lose electrons based on environmental conditions. Or consider semiconductors; they are not always conductive or insulating but can change their behavior depending on the situation. This adaptability is the foundation of our ability to build computers.

It is no surprise that we are carbon-based life forms because the carbon element has the flexibility and wide adaptability spectrum to become either C+4 or C-4 depending on environmental conditions. This has played a significant role in making it our fundamental building block. Carbon is, in a sense, alive, but not in a way that fits our standard definitions.
