Why is this clone failing, and is there a better way to launch players?

I'm not sure if I'm going about this the right way, but what I'm trying to do is create a BodyVelocity to the player's HumanoidRootPart then clone a script inside of that to destroy it. The code is here:

local replicatedStorage = game:GetService("ReplicatedStorage")
local debounce = false


function onTouched(other)
	if debounce == false then
		local rootPart = other.Parent:FindFirstChild("HumanoidRootPart")
		if rootPart ~= nil then
			local vol = Instance.new("BodyVelocity")
			vol.Velocity = Vector3.new(200, 0, 0)
			local clone = replicatedStorage:FindFirstChild("scripts").destroy:Clone()
			clone.Parent = vol
			vol.Parent = rootPart
			wait(1)
			debounce = false
		end
	end
end

script.Parent.Touched:Connect(onTouched)

It errors when trying to clone from replicatedStorage with: attempt to index function with 'Clone'

I am also completely open to other ways of launching a player.

At the local clone, you did .destroy:Clone() and destroy is a feature you can do so the script thinks you're trying to destroy something named clone

Like this

local replicatedStorage = game:GetService("ReplicatedStorage")
local debounce = false


function onTouched(other)
    if debounce == false then
        local rootPart = other.Parent:FindFirstChild("HumanoidRootPart")
        if rootPart ~= nil then
            local vol = Instance.new("BodyVelocity")
            vol.Velocity = Vector3.new(200, 0, 0)
            local clone = replicatedStorage:FindFirstChild("scripts").["destroy"]:Clone()
            clone.Parent = vol
            vol.Parent = rootPart
            wait(1)
            debounce = false
        end
    end
end

script.Parent.Touched:Connect(onTouched)

Why do you need a seperate script to destroy it? You can use game:GetService("Debris"):AddItem(Item,Duration) It will destroy Item in Duration seconds. Matt's answer is correct, but they didn't fix the problem. Changing destroy to DestroyScript fixed the problem, but adding ["destroy"] still comes out as scripts.destroy. It just allows you to add more to the string like ["destroy".. "red"] would be scripts.destroyred

--Possible easier way, unless you absolutely have to have a seperate script to destroy it
--replace local clone --- vol.Parent with
--game:GetService("Debris"):AddItem(vol,10) -- This will destroy vol after 10 seconds

local replicatedStorage = game.ReplicatedStorage
local debounce = false


function onTouched(other)
	if debounce == false then
		local rootPart = other.Parent:FindFirstChild("HumanoidRootPart")
		if rootPart ~= nil then
			local vol = Instance.new("BodyVelocity")
			vol.Velocity = Vector3.new(200, 0, 0)
			local clone = replicatedStorage:FindFirstChild("scripts").DestroyScript:Clone() -- Naming your script destroy was your issue, renaming it fixed the problem.
			clone.Parent = vol
			vol.Parent = rootPart
			wait(1)
			debounce = false
		end
	end
end

script.Parent.Touched:Connect(onTouched)
