What you seem to be missing here is that "freewill" is not compatible with in-determinism (random causes and or uncaused events).
In order to "solve" the "freewill" question we don't need to know "the origin of the initial singularity" (which is beyond our epistemological limits).
In order to "solve" the "freewill" question, we only need to know that ALL events are either CAUSED or UNCAUSED or some combination of the two.
(IFF) all events are CAUSED (THEN) determinism makes your decisions (not "you")
(IFF) SOME events are CAUSED and some are UNCAUSED (THEN) UNCAUSED (indistinguishable from random) makes your decisions for you (not "you")
There is no escape.
There is no haven of ignorance in which "freewill" can hide itself.
All motives (goals) that drive your "decision making" are caused by previous events.
And the only "alternative" is that some of your motives (goals) are "uncaused" (making them indistinguishable from random).
A random action is not an action that you "choose".
A random action is not an act of WILL.
