Creating a randomly generated world with grids?

So i'm trying to make a world that generates itself randomly in a grid in a radius around the player but i have no idea how to and methods of doing something like this?

game.Players.PlayerAdded:Connect(function(plr)
    plr.CharacterAdded:Connect(function(char)
while wait(5) do

    for i,Chunk in pairs (game.Workspace.Folder:GetDescendants()) do
        if Chunk.Name == "Base" and Chunk:IsA("Part") and (Vector3.new(char.HumanoidRootPart.Position.X,49,char.HumanoidRootPart.Position.X) - Chunk.Position).Magnitude <= 120 then
            for i,subchunk in pairs(game.Workspace.Folder:GetDescendants()) do
        if subchunk.Name == "Base" and subchunk:IsA("Part") then
                if (Chunk.CFrame * CFrame.new(64,0,0)).X == subchunk.CFrame.X then

                    else
                local model = game.ReplicatedStorage.TestChunkSize1:Clone()
            model.Parent=workspace.Folder
model:SetPrimaryPartCFrame(Chunk.CFrame * CFrame.new(64,0,0))
                                               end
            end
        end
        end
    end

end


end) end)
