Does magic exist? It all depends on how you define magic.
I believe what we have done, through science, is very magical. We can talk to people on the other side of the world in less than a second, we can leave our earthly home to places beyond, like the moon or mars. We can see thousands of light years away, thousands of years in the past, through telescopes that move at thousands of kilometres per hour. We can create electronic brains that can do billions of calculations a second and can still fit in your pocket. We can cure the incurable, solve the unsolvable, do the impossible.
Science is magic, the thing is it turns out magic isn't easy. There isn't some sure way where you can go "Oh I will snap my fingers and do some stuff and suddenly things will happen!", no, it turns out magic requires work, it requires understanding.
Does magic exist? Yes, it exists and we call it science.
