I dont know whats wrong with my Admin script?

I am trying to conduct my own Admin Commands script, but the script isn't working, the Output says that 'find' is a nil value, but I dont understand, here is the script;

wait(0)
print("Admin Loaded")
admins={"TheeDeathCaster"}
game:service("Players").PlayerAdded:connect(function(plr)
for i=1,#admins do
if plr.Name:lower()==admins[i]:lower()then
plr.Chatted:connect(function(msg)
if msg:lower():sub(1,5)=="kill/"then
find=game:service("Players"):FindFirstChild(msg:sub(5))
if find~=nil then
find.Character:BreakJoints() --It said the error was here, attempting to call find (a nil value)
print("Killed "..find)
else
print(find.." does not exist")
end end
end)
else
print("nil Player")
end end end)

There is no :service method for DataModel/game. You can do game.Players though or game:GetService("Players").
