Lost in Creative mode

I am on creative and was exploring the Nether. I happened to travel very far without realizing it and could not find my way back. I decided to try and make another nether portal but that sent me to the middle of an ocean.

I can't kill myself and go to spawn because I am on creative if anyone can help that would be great.

Since you're in creative you can give yourself a compass and fly to your spawn point (which the compass always points to). Don't try and make your way back via The Nether as your compass won't work there; unfortunately this means you're in for a much longer trip than you went through the nether, but it should be a straight-shot, due to flying.

Unlike digging straight down to the Void (which will work and kill you even in Creative) you won't have to make an ugly hole to the center of the earth, if you care about that.

You can kill yourself in creative: dig straight down and fall in to the void. You will die and respawn at the spawn point.

Push F3, and travel in a direction that puts your X and Z coordinates towards 0.
