A potential argument for existence of God

[Cephus]

Hi everyone, 

So last night, before falling asleep, I thought of a potential argument for the existence of God (and this isn't the reason why I believe in God), and would like to see feedback on whether it's a good argument or not and why. So this is how it goes:

The universe had a beginning. Therefore there can be only two possibilities: either it was created from nothing, or it created itself. The universe couldn't have created itself because it was nonexistent before its creation. And if it was created from nothing, because nothing existed, there were no factors to narrow down creation to a certain kind of thing, and thus nothingness had an infinite amount of options to choose from to create something. We know that it did choose a particular one. Therefore, by choosing a particular one, it (nothingness) discarded all the other options. Hence, nothingness has an inherent quality of picking certain things and not picking others, and also the power to create its chosen option. But how can nothingness have such qualities of power and choosiness; it is nothing; it  has no quality or disposition! If nothingness does indeed have these qualities, then it is no longer nothing; it would be a powerful, choosy being that has the ability to choose freely (because there are no factors to limit its choice) and hence has a free will, and is uncreated. Sounds a lot like God!

Keep in mind that the resulting "nothingness" with its mentioned qualities does seem to match with the Islamic concept of God, because in Shia Islam, Allah (God) is nothing but His Qualities; His Qualities are Him, and are His Essence.

This is nonsense.  By definition, nothing can ever create itself.  To create it must exist, therefore it doesn't need to be created.  This is a really obvious example of a false dichotomy.  There isn't two possibilities.  There are many.  You're just ignoring the majority of them.  There is nothing that says the universe was created at all.  In fact, all the evidence shows that it was likely formed by entirely natural means.  Further, nobody says that it came from nothing.  Anyone who makes that claim has no clue about science.

This whole thing isn't new but it has been soundly and completely discredited before.  Try again.
