Same reason the chicken crossed the road. Though several theories are given as to why the chicken crossed the road, a priori, it has crossed the road so there is a reason. In this same spirit, we know that the elite are hiding the truth about the Earth because the Earth is flat and they aren't admitting it. Whoa, don't put words in my mouth, I have never said that. I said that gravity on Earth is an illusion. And regardless, it still doesn't change the fact that the claim that a force has to be visible to exist is ridiculous no matter what is the theory to which you subscribe.
