Why are atoms alive in organisms but not in non-living objects?

We are made up of atom & we are alive
But a pen is also made up of atom but
it is not alive

You are asking how it can be that some things made up of atoms are alive and other things made up of atoms are not. You will find some answers if you google for "emergent property".

Further discussion will take us outside the scope of science and questions about science, so this thread is closed.
