Damn ... I'm late to this party.
Well, I've read the thread and although a lot has been going on since the OP ... I think I'll go ahead and address that.
(btw ... thanks to @shnozzola a couple of posts of mine in the thread).

Ok then, lets get to it...
The universe was created in the big bang, or some other process that we don't know about, doesn't really matter. Then hydrogen made stars which made more and more elements, And any ways we end up here, earth. Life is spontaneously created and now humanity flourishes. That is all fine and dandy.
Okay. I would re-word 'created' to 'came into existence' but hey ...
However, there is no natural way to create a random event. f you drop a dice the exact same way onto the exact same surface from the exact same height it will always give you the same value.
The dice analogy is a bad example. Also, note that we do have artificial, human developed systems in place to create situations with random, unpredictable results ... i.e. the lottery machine with the numbered balls.
... but okay ... for the sake of argument, I'll grant this on the basis that I am taking this as a thought experiment.
Random does not exist in nature, it is a purely human concept that more refers to our inability to predict.
I'm in thought experiment mode to I'll grant this for the sake of argument ... I don't want to spend time explaining the stochastic properties of the universe at quantum levels ...
This then implies that every thing that has ever happened is the effect of previous events. There is no chance. The entirety of human history is defined by how the big bang went of and how the hydrogen came together into the original stars.
Okay. Let's assume this.
Every thought you are currently happening has no meaning
Why? Why would my thoughts have no meaning? Just because they are caused by deterministic events in this hypothetical universe doesn't mean the thoughts themselves don't have meaning. They mean something to me.
it is simply a chemical reaction and a result of previous events. So this brings us to free will, every action you have and will take has been predetermined by nature. You can try and break that by doing something random, but you are unable it is simply action and reaction. We cannot change the future, because the future is already been determined.
Yup ... in a fully deterministic universe, where there were no random events, then indeed we would have no 'free will' and the future would be determined.
So in conclusion I would contend that in a Godless universe there is no free will...
I thought you said "god" had nothing to do with this discussion. So I don't understand why you would feel the need to describe it as "godless" in your conclusions.
It serves the same purpose to mention anything that doesn't exist in this hypothetical universe ... for example:
"So in conclusion, I would contend that in a universe without Bigfoot there is no free will."
The lack of free will in this universe you are describing has nothing to do with it lacking a god.
... and now, can I ask ... what is the point of your OP? To demonstrate that in a fully deterministic universe that lacks randomness and the existence of a god there is no free will? Okay... granted. So what now?
----------
Here's an additional note to clarify my actual position on free will and the universe ...
The universe has both deterministic and stochastic (random) properties. Neither of these give rise to 'free will'. The future is not predetermined. Many things can be predicted to a certain degree of accuracy, others are impossible to predict.
For more info, and in case you missed shnozzola's reference to it, here is my position on 'free will':
