Look through history, do people deny things as possible because they don't understand? You don't understand God, so it must be us that's brainwashed.
If you don't understand physics, does that make the physicist an idiot or shill. See how that works?
If I told 150 years ago you could talk to hundreds of people at once all around the world on a device the size of a small rock on a place called 8kun, you'd have probably thought me insane.
Just because you don't understand something, doesn't mean it's not true.
God Bless.
