Acrophobia

Fear of heights be damned, the Earth is flat, that’s easy enough to prove
If only I could walk up to the edge, but I can’t bring myself to move
I don’t need to take a photo just to make you see
The edge is over there on the horizon, it’s as plain as day to me

I know the edge must have a high lip holding all the water, just like a baking tin
Logic says it must be high enough to keep all the things and people contained within
Some say there is no edge, that Antarctic ice sheets go on to infinity
Clearly, once it melts it would all simply pour out, including all the sea

There must be dirt, mountains, beaches, oceans, and icebergs right up to the wall
If there was nothing to make the edge, clearly all earthly things would start to fall
It’s probably made of iron ore, or something magnetic and strong, you see
To bring a compass needle bearing north, and for the likes of thee

(Prompt: The earth is actually flat, you look over the edge and what do you see? Describe it. Disclaimer: I am in no way, shape, or form a flat-earther.)
