Why wont this script work?

I made a script for a NPC with a humanoid property to move them from place to place but when I use it on a Model without a humanoid property it doesn't work

Script is here for the humanoid NPC

local part = game.Workspace.Node1
local node = game.Workspace.Node2

while true do
script.Parent.Humanoid:MoveTo(Vector3.new(-13, 0.59, 31) )
wait(5)
script.Parent.Humanoid:MoveTo(Vector3.new(-13, 0.59, 93) )
wait(3)
script.Parent.Humanoid:MoveTo(Vector3.new(-7.2, 0.59, 93) )
wait(1)
script.Parent:remove()
end

script for Model without humanoid

local Van = Script.Parent

while true do
script.Parent:MoveTo(Vector3.new(47.2, 0.19, 43) )
wait(5)
script.Parent:MoveTo(Vector3.new(-5.6, 0.19, 43) )
wait(3)
script.Parent:MoveTo(Vector3.new(-32, 0.19, 43) )
wait(1)
script.Parent:MoveTo(Vector3.new(-89.4, 0.19, 43) )
wait(5)
script.Parent:MoveTo(Vector3.new(-105.4, 0.19, 43) )
wait(1)
script.Parent:remove()
end
