A fact can be proved by either direct evidence or circumstantial evidence, or by both.
If an eyewitness testifies about what the witness saw, that is an example of direct evidence.
If the ground is bare when you go to sleep but is covered with a blanket of snow when you awake, this is circumstantial evidence that it snowed while you were asleep.
The law makes no distinction between direct and circumstantial evidence. You should give all evidence the weight and value you believe it is entitled to receive. A conviction may be justified on circumstantial evidence alone if the circumstantial evidence has such probative force as to enable you to find the Defendant guilty beyond a reasonable doubt.
