If Aliens arrive with their tech to traverse world wouldn't our weapons pretty much look like sticks and stones to them? Also how do we not catch a disease from them or vice versa?

Any vehicle that can cross interstellar space in a reasonable time also has enough energy to destroy a planet, simply by crashing into it.

Depends on the size of the craft. If it is only a few meters across, I think it would just burn up in the atmosphere before it even reached the ground.

If it burns up in the atmosphere with relativistic speed, it burns up the atmosphere.

True, but damage still depends on craft size. At the really small end you’re basically just talking about a normal cosmic ray.
