We can describe the electric force as the result of an electric field,
F = E q
Consider the force on a small "test charge" in the neighborhood of a positive charge Q.
Move the small "test charge" q around and investigate the force F that it experiences at different places near Q.
We will find an electric field originating on a positive charge.
Likewise, we will find an electric field terminating on a negative charge.
