The ground appears to rise, yes. From the perspective of the person looking into the horizon, the ground will appear to rise to eye level, that is how perspective works. It seems like you grasps this concept, so well done. If you want to call it an optical illusion, that is fine by me, I personally call it perspective though.
Based on this concept, you can understand that the higher you get, the farther can you see over our plain earth. But even on Mount Everest a horizon will form at eye level, and 100% optical.
I am saying that a laser from a top of a mountain, going over the ground, will converge at the horizon as it gets far enough away, from the perspective of the person a top the mountain. The person at the mountain will not be able to distinguish between where the ground is and where the laser is, as the laser gets farther and farther away, that is due to how perspective works. All parallel lines going away from you will converge at a single point. To see further, you need to increase your height, or get a optical zoom device, and from your perspective, the horizon will form further away from you, and you will be able to track where the laser is going for a longer time, and over a greater distance.

So the object that blocks my laser from hitting the moon is....the ground? That's what you're saying?

It's not going "over the ground", it's 6.8 degrees. Is that beam going to touch the ground or not?
From our perspective, the ground and the beam will converge at the horizon.
