Is it possible to get a shiny mew?

Excuse me, I'm curious about the possibility of acquiring a shiny mew in the world of Pokémon. Could you please elaborate on whether this elusive and coveted creature is indeed attainable? I've heard whispers of its existence, but I'm not entirely sure if it's merely a myth or if there's a legitimate way to add one to my collection. I'd appreciate any insights or guidance you might have on this matter.
