However, you are forgetting that the Dwemer used loads of metaphysical concepts and objects which don't exist in the real world. For example, we can assume that the Soul Gems found inside Dwemer robots are the power sources for the robots; the closest thing we would have to that would be batteries. Numidium was also originally supposed to be powered by Lorkhan's Heart, and as far as I know, there isn't a heart of a dead god lying somewhere around Earth.

What we should also not forget is that the Dwemer might be better in robots, but we've never seen any kind of Dwemer DEW (Directed Energy Weapon), Nanotechnology, nuclear fission technology, hell, even normal guns. They'd have no way to stop a incoming Nuke. They'd also be severly underpowered on the open battlefield, even if they'd use their robots. Earth has RPGs, anti-tank weaponry, etc.
