programmed - alive why

programmed

two options;
each one of us humans has come up with the idea of happiness and unhappiness
or
we are somehow programmed to have these things,
happiness and unhappiness,
which are emotions

when a baby is born it usually starts screaming
this is a sign of emotion

does it think
"i am a baby , i should start screaming like a baby does"
or is it programmed ?

you could say the baby does not really have emotion.
but when do we have real emotion?
how do you say what is real emotion?
is a 2 year old screaming having real emotion?

it is all real emotion.
animals (like dogs) have real emotions.
some dogs even get put on antidepressants.

but we don't choose to have emotions.
we are born with them.
they are programmes in the primitive part of our brains,
called the amygdala and limbic system.
