Human beings are alive. They are not inanimate. So what is the definition of life?

So you have to include the idea of a self-sustaining chemical system. The system we use on earth is the copying of the DNA molecule.
It is a complex molecule which has the ability to code for proteins which make up the body of the animal and to make copies of itself.
Nobody tells this molecule to copy itself, It just does it. Without this ability there is no life.
How can you emulate this ability without actually having this ability to copy oneself?
A picture of a human being may be very realistic but it is not alive itself.
On the stage at Stratford ,Ontario I saw a man pretending to be King Lear. But he really wasn't.
Pretending to be alive isn't being alive. To be alive you need to possess a molecule which copies itself.
Life is an artifact of the very nature of physics and chemistry plus evolution.
Either an entity possesses these characteristics or it doesn't. You can't fake it.
