If someone to today from as little as 500 years ago. Certainly if you bring them from "biblical" times and show them our life and powers today and they would be awed:
We are gods!
We raise the dead, we invoke lightening, we hold back the floods and create them. We fly. We speak and see across the earth. We travel to other worlds. We can, if we choose, shatter a mountain. We know more about our universe than the gods they used to worship back then. We are as powerful and more knowing than they were able to imagine.
