Is there a flaw in the Kalam Cosmological argument?

Why doesn't this argument work for the cosmological argument for atheism? 1.)Anything that exists needs a cause **(Check) ✔** 2.)The Universe needs a cause **(Check)✔** we know that, because the universe is running down, and something that is running down must have started at some point. The second law of thermodynamics states that the universe is running out of usable energy and if you doubt this, look in the mirror you’re aging and running down just like everything else. 3.)So there is a First Cause **(Check)✔** 4.)The First Cause requires a decision to initiate a effect **(Check)✔** **5.)** The First Cause is an unintelligent impersonal unconsciousness, which has only the ability to decide whether to create the universe or not create the universe spontaneously out of itself, so a Yes and No decision. When **(5.)** means Yes and No, It means that it is impersonal as to a frog which can only decide a limited amount of things, e.g to eat the bug or not eat the bug.**(❓❓❓)** 6.)Therefore Allah does not exist.**(❓❓❓)** Now why does this argument not work? How should a Muslim respond to this?
