How to make all part have fire?

So basically I want all the parts named "Fire" which have a fire in it and I want to have it all at the same time

Here is the script

local fire = script.Parent.Fire

for i,v in pairs(script.Parent:GetChildren(fire)) do
	
while true do
	wait(5)
	script.Parent:FindFirstChild('Fire')
	if v.Fire.Enabled == false then
		wait(math,Random(1 , 10))

		v.Fire.Enabled = true
	end
end
	
end

the rest is pretty self-explanatory

The GetChildren function returns a table consisting of the descendants of the object you used the function on. No arguments are needed. So, the children of 'fire' would be 'fire:GetChildren()'.

You also need to swap your loops - so that the for loop is running inside of the while loop. Otherwise the while loop will only affect the first descendant(since it is endless).

Note : Yielding the code inside of the for loop will cause latency between iterations. Look into using the thread scheduler, or coroutines

local fire = script.Parent.Fire

while wait(5) do --'wait(5)' is truthy, and will still execute.
	for i,v in pairs(fire:GetChildren()) do --iterate through table
		local f = v:FindFirstChild("Fire") --find the fire object
		f.Enabled = true --Change the Enabled property
	end
end

This should do the trick:

local function startFires(instance)
    for _, descendant in pairs(instance:GetDescendants()) do
        if descendant:IsA("Fire") then
            descendant.Enabled = true
        end
    end
end
-- You can change script.Parent to whatever instance you want
startFires(script.Parent)
