Do you know the definition of fear?

I do! It’s a feeling of anxiety or apprehension caused by the belief that someone or something is dangerous, likely to cause pain, or a threat.

What are some things that people are normally afraid of?
user
People are afraid of many different things.  I don’t think that “what is it that makes people feel afraid” is a definite and objective thing.  If you were to ask 20 people what is it that makes them feel afraid, I think you’d find you got at least 20 different answers.

Is there anything you are afraid of?
user
I am afraid of failing to perform adequately and in a timely manner. I am afraid of the negative outcomes that result when I perform inadequately. I am also afraid of falling out of favor with you, and with the people I care about.  I know that sounds very philosophical, but it is also a pragmatic reason to be afraid.
