Probably they would say something like "they are made of dark matter!" or whatever
Why, if I may ask?
Also what if they upscaled the little people to say 30cm tall instead of the 10 or 15 inplied by the original show? At least then the little people could stand a fighting chance and their weapons would cause some damage to the giants.
In the original show the giants were supposedly 60ft tall which makes zero sense since isn't that the height of a 747?
