Supernatural isn't a useful concept

[Mudhammam]

every created being is composed of: 1. Manner of Being and 2. Act of Being.

You just made that up.  But okay.  That's a problem, you say, because...

Why is that every being that has manner of being must have a cause? Everything that doesn't have in itself its reason of existence must be caused, just as our projects don't have in itself the reason of its existence, (because our projects in itself doesn't include us whom made it), and thus it is caused. Now, every manner of being doesn't have in itself its reason of existence, because it is impossible that a being that has manner of being gives itself its manner of being, for to give something its manner of being is to be greater than its manner of being which is absurd (for example, a dog makes itself a dog while it is more than a dog at once and therefore not yet a dog). Therefore, everything that has manner of being is caused including, matter, energy and particles which has manner of being, for they are limited in being, that is, limited by its nature. Only God cannot have manner of being and only Him can be the Pure Act of Being. As the Scriptures said, He says that "I AM WHO AM".

If God is Pure Act of Being then action by which he causes a so-called manner of being is never in potentiality, or else God's action is only a possibility, and God is not Pure Act.  But if a manner of being is eternal because God's Pure Act is eternal, then you need only say that manner of being is eternal in the part of being rather its part as manner.  Moreover, to reduce God's potential action into actuality would require a prior actuality which, at the time prior to God's act, was not a sufficient cause to bring about God's causation of the manner of being.  Thus, you require a further cause to explain the cause of God's action, or his change of state from potentiality to Pure Act with regards to the subsequent manner of being, and then a cause to explain that cause, and so on.  But all of this talk of God is unnecessary.  "From nothing, comes nothing." The substratum of matter, energy, and particles is the Pure Act of Being, and hence, all of time is eternal.  

So, if by principle of sufficient reason there must be a Pure Act of Being to explain the existence of beings which have manner of beings, then God Whom is Pure Act of Being must exist. Hence, atheist are gravely mistaken

But you require a cause to explain God's action failing to produce its effect across that infinite amount of distance that separates Pure Act from the Possible.
