How do I move something from Workspace to ReplicatedStorage?

local target1 = CFrame.new(0 - 178, 79, 0)
local target2 = CFrame.new(0 - 178, 205, 0)

if #(game.Players:GetChildren()) > 1 then
    for i, player in pairs(game.Players:GetChildren()) do
        repeat wait() until player.Character ~= nil
        if player.Character.Humanoid.Health ~= 0 then
            game.Workspace.Spawn.Spawn.Enabled = true
            game.Workspace.Lobby.Spawn.Enabled = false
            game.ReplicatedStorage.arena1.Parent = workspace
            player.Character.Torso.CFrame = target1
        end
    end
end

if #(game.Players:GetChildren()) < 1 then
    for i, player in pairs(game.Players:GetChildren()) do
        repeat wait() until player.Character ~= nil
        if player.Character.Humanoid.Health ~= 0 then
            game.Workspace.Spawn.Spawn.Enabled = false
            game.Workspace.Lobby.Spawn.Enabled = true
            game.Workspace.arena1.Parent = ReplicatedStorage
            player.Character.Torso.CFrame = target2
        end
    end
end

Please help me! (I've asked a lot of questions)
