I don't think it is impossible at all. Maybe with today's technology it is, but who knows what humans will discover and be capable of in the next 100 years. It frustrates me seeing posts from people like you thinking our basic understanding of physics and engineering is the pinnacle of science- which is both vacuous and stupid.
I'm sure we would have still left the trees if everyone was like you, but we probably wouldn't have an airplane or a computer. We probably would not be able to trap light. We probably wouldn't be uncovering quantum secrets, detecting extra-solar planets, or visiting the moon either. We are at the brink of learning how to manipulate space and, in the future, we will only learn more.
