Your OP does not include, at least directly, a counter to an Aristotelian Cosmolgical Agrument, since that kind of an argument allows for the Universe/Reality to be eternal. I haven't read all of the other comments but I will. I am interested on your thoughts on this argument:

1. We perceive a series of efficient causes of things in the world.

2. Nothing exists prior to itself.

3. Therefore nothing [in the world of things we perceive] is the efficient cause of itself.

4. If a previous efficient cause does not exist, neither does the thing that results (the effect).

5. Therefore if the first/prime thing in a casual series does not exist, nothing in the series exists.

6. If the series of efficient causes ordered per se extends ad infinitum into the past, then there would be no things existing now.

7. That is plainly false (i.e., there are things existing now that came about through efficient causes).

8. Therefore efficient causes do not extend ad infinitum in a per se casual series.

9. Therefore it is necessary to admit a first efficient cause, which is uncaused.

If you don't know what a per se casual series is, read a few paragraphs of from this link:

Note that this argument allows for the Unverse to be eternal and even for there to an infinite amount of cause in a non per se casual series. For instance, there could be an infinite amount of train cars, but there still needs to be a locomotive to explain the motion.
