Minecraft wiki entry for Creative, associated text: Players in Creative mode are unable to receive damage. However, going too far into the void still kills the player (in Java Edition, while in Bedrock it is possible to stand on it), but the player can fly around in the void provided they do not descend below Y=-128. This, the /kill command, and external editors are the only way to die in Creative mode.‌[Java Edition only] Creative players in Bedrock Edition are completely invulnerable, just like in Spectator mode.
