How do I make the explosion instance not create until it's Parent is made?

So, I have a script where, when I step on a brick, the limbs of "Human" catch fire. After 3 seconds, I want an explosion to occur in the the Human's Torso. The problem is, the explosion is created in the Baseplate and doesn't parent to Torso after I clone it. All help is appreciated! Here's the script:

local part = script.Parent
local db = false

function explode(hit)
	local human = hit.Parent
	local explosion = Instance.new("Explosion")
	local fire = Instance.new("Fire")
	local myArray = {"Left Leg","Right Leg","Left Arm","Right Arm"}
	if human then
		if not db then
			
			db = true
			
			for i,v in pairs(myArray) do
				fire:Clone().Parent = human[v]
			end
			wait(3)
			explosion:Clone().Parent = human
			
			db = false
				    
				end
			end
		end
	

part.Touched:connect(explode)

Also, output isn't giving any errors.

You are creating the explosion too early. Create the explosion right before you are going to use it. Also it should be Human.Torso
