how do I make a part become the same orientation as another part? [SERIOUS HELP NEEDED]

I have a script that where ever you click, a spell will fly there. If it hits a object with a humanoid, it will damage it and stun it. If it does not, then it will make a burn mark on where it is hit. My problem is that if a burn mark is made anywhere except the floor, it will stick out. For example, this is it on the floor:

But if I shoot it at a wall, this is how it will look:

Does anyone have any ideas how to make it rotate so it looks like it does on the floor? Here is the script. If you have any questions, comment them!

"a" is mouse.hit that I got from a local script

hit is the burn mark
