How To Make This Boss Battle Script Only Happen To Specific Players Who touch A Block?

I want to make it so that if a player touches an object then a boss battle script runs for them and them only, (Boss Battle Script by Poncho Kings.) The Boss Battle Script is in the Server Script Service and the touch script is in a block in the Workspace, the Boss Battle Script is disabled until the block is touched.

(Boss Battle Script)

local function fireballChallenge()
	
	for i = 1,3 do

		for i,player in pairs(game.Players:GetPlayers()) do
			if player.Character then
				local fireball = game.ReplicatedStorage.Fireball:Clone()
				local fireball2 = game.ReplicatedStorage.Fireball2:Clone()
				local fireball3 = game.ReplicatedStorage.Fireball3:Clone()
				local fireball4 = game.ReplicatedStorage.Fireball4:Clone()
				local fireball5 = game.ReplicatedStorage.Fireball5:Clone()
				local target = game.ReplicatedStorage.Target:Clone()
				local target2 = game.ReplicatedStorage.Target2:Clone()
				local target3 = game.ReplicatedStorage.Target3:Clone()
				local target4 = game.ReplicatedStorage.Target4:Clone()
				local target5 = game.ReplicatedStorage.Target5:Clone()
				
				target.Parent = game.Workspace
				target.CFrame = (player.Character.HumanoidRootPart.CFrame - Vector3.new(0,3,0)) * CFrame.Angles(0,0,math.rad(90))
				target2.Parent = game.Workspace
				target2.CFrame = (player.Character.HumanoidRootPart.CFrame - Vector3.new(-20,3,0)) * CFrame.Angles(0,0,math.rad(90))
				target3.Parent = game.Workspace
				target3.CFrame = (player.Character.HumanoidRootPart.CFrame - Vector3.new(20,3,0)) * CFrame.Angles(0,0,math.rad(90))
				target4.Parent = game.Workspace
				target4.CFrame = (player.Character.HumanoidRootPart.CFrame - Vector3.new(0,3,20)) * CFrame.Angles(0,0,math.rad(90))
				target5.Parent = game.Workspace
				target5.CFrame = (player.Character.HumanoidRootPart.CFrame - Vector3.new(0,3,-20)) * CFrame.Angles(0,0,math.rad(90))
				
				wait(0.5)
				
				fireball.Parent = game.Workspace
				fireball.CFrame = target.CFrame + Vector3.new(0,30,0)
				fireball2.Parent = game.Workspace
				fireball2.CFrame = target.CFrame + Vector3.new(20,30,0)
				fireball3.Parent = game.Workspace
				fireball3.CFrame = target.CFrame + Vector3.new(-20,30,0)
				fireball4.Parent = game.Workspace
				fireball4.CFrame = target.CFrame + Vector3.new(0,30,20)
				fireball5.Parent = game.Workspace
				fireball5.CFrame = target.CFrame + Vector3.new(0,30,-20)
				
				wait(2)
				
				target:Destroy()
				target2:Destroy()
				target3:Destroy()
				target4:Destroy()
				target5:Destroy()
			end
		end
		wait(1)
	end
end

while wait(5) do
	
	fireballChallenge()
	
end

(Touched Script)

local block1 = game.Workspace.FrontBlock5
local block2 = game.Workspace.FrontBlock6
local block3 = game.Workspace.BackBlock5
local block4 = game.Workspace.BackBlock6
local BossBaconCell = game.Workspace.BossBaconCell
local Players = game:GetService("Players")

script.Parent.Touched:Connect(function(hit)
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
	if player then
		wait(0.5)
		block1.CanCollide = true
		block2.CanCollide = true
		block3.CanCollide = true
		block4.CanCollide = true	
		
		BossBaconCell.Part10.CanCollide = false
		BossBaconCell.Part11.CanCollide = false
		BossBaconCell.Part12.CanCollide = false
		BossBaconCell.Part9.CanCollide = false
		
		game.ServerScriptService.BossFightScript.Disabled = false
		if game.Workspace.FrontBlock5.CanCollide == false then
			wait(10)
		end
	end
end)

How would I make it so that the Boss Battle Script only runs for the person who touches the block? Please Help.

Thank you!
