How do I make a team splitter?

So I wana make a script that picks a sertain number of people from the entire server to become part of one team and the others to be on another, But also to have the Team Names on the leaderboard. Any ideas how I would go about doing this, Thanks in advance.

players = game.Players:GetChildren()  -- gets current players
randomp = players[math.random(#players)]  -- picks random player
print(randomp.Name .. " is it") -- tells us who the random player is
--stuff for it player or random
for i,v in pairs(players)  do -- iterate the player table
	if v.Name ~= randomp.Name then -- whoever isn't 'it', will tell us who isn't
		print(v.Name .. " is not it") -- tells us who
			--stuff if not it
	end
end
