Pixie: a supernatural being in folklore and children's stories, typically portrayed as small and humanlike in form, with pointed ears and a pointed hat.

"Which is more logical? A magic sky pixie wiggles his magic wand and poofs everything into existence out of nothing, Or the big bang causes the universe to expand and lets energy turn into matter?"

Your question, well done.

A magic sky pixie, aka the Magic Man, is not real because the thing is impossible. The Easter Bunny has the same problem. It's impossible.

Everything that ever happened was a natural process. Supernatural bullshit is for the Dark Ages, not the 21st century.
