Why does my npc attack my other npc?

So I have a npc that attacks anything humanoid this is the script.

function findNearestPlayer(Position)
    wait(0.3)
    local List = game.Workspace:children()
    local Torso = nil
    local Distance = 20
    local Temp = nil
    local Human = nil
    local Temp2 = nil
    for x = 1, #List do
        Temp2 = List[x]
        if (Temp2.className == "Model") and (Temp2 ~= script.Parent) then
            Temp = Temp2:findFirstChild("HumanoidRootPart")
            Human = Temp2:findFirstChild("Humanoid")
            if (Temp ~= nil) and (Human ~= nil) and (Human.Health > 0) then
                if (Temp.Position - Position).magnitude < Distance then
                    Torso = Temp
if game.Players:GetPlayerFromCharacter(Temp) then
                    Distance = (Temp.Position - Position).magnitude
                    end
                end
            end
        end
    end
    return Torso
end


while true do
    local target = findNearestPlayer(script.Parent.HumanoidRootPart.Position)
    if target ~= nil then
        script.Parent.Humanoid:MoveTo(target.Position, target)
    end
end

Why does he attack anything thats humanoid and not only players? I put line 17 in but it still doesn't work. I want him just to attack players. The duplicated npc has the exact same everything from the first one. I just clicked ctrl d and moved my npc2 next to my npc 1 to test. The script I pasted in my post is the follow script which is the movement. There is also a damage script and animation script for walking and stuff but that doesnt matter.

Hello! Here is how to fix it:

function findNearestPlayer(Position)
    wait(0.3)
    local List = game.Workspace:GetChildren()
    local Torso = nil
    local Distance = 20
    local Temp = nil
    local Human = nil
    local Temp2 = nil
    for x = 1, #List do
        Temp2 = List[x]
        if (Temp2.className == "Model") and (Temp2 ~= script.Parent) and (game.Players:GetPlayerFromCharacter(Temp2)) then
            Temp = Temp2:findFirstChild("HumanoidRootPart")
            Human = Temp2:findFirstChild("Humanoid")
            if (Temp ~= nil) and (Human ~= nil) and (Human.Health > 0) then
                if (Temp.Position - Position).magnitude < Distance then
                    Torso = Temp
if game.Players:GetPlayerFromCharacter(Temp) then
                    Distance = (Temp.Position - Position).magnitude
                    end
                end
            end
        end
    end
    return Torso
end

I have experience with NPC's so I hope this helps. Other than that, everything is good!

Sorry I don't know much about scripting but I'm pretty sure the script tries to find "Humanoid" and then goes for it. Maybe try changing the NPC Humanoid's name to "NPCHumanoid" and that should fix it.
