What is life?
Depends on how much you want to grasp.

We can use a few definitions:

It is an iterative loop
of gathering input,
interpreting it,
deciding on a course of action,
doing it,
repeating it.

It is a process of molecular biology
building machines,
which transfer [genetic] information,
and evolve into ever more complex forms
in a growing web of interactions.

It is a conscious experience
- maybe that's all it is -
maybe it is nothing special.
but I sure want to know if it
is multi-level, does my body
experience various levels of
experience? Is it something
like to be my cells?
Is it something to be a country,
the internet, all of interconnected
life?

What is it?
There is no single answer.
All of it is true. All of it is life.
