Target Nearest Player Instead?

Here's my code. I'd like to take this and instead make MyTarget the nearest player instead of a random one. This will ensure the enemy targets a Survivor and not somebody who has already died. I have no idea how to do this.

	local humansFound = {}

	local players = game.Players:children()

	if (#players < 1) then return end

	local i = math.random(1, #players)

	myTarget = players[i].Character

Any help is greatly appreciated! Thanks!
