Hi, Perplexity,
I do not think anyone has ever claimed that humanity, earth or the entire universe is infinite. Being around for a long time is just a long time - but, infinite is without end. And, this is where your argument fails - God alone is infinite.
Mackie’s argument is displayed in the first two sentences - and we are not talking about an, ‘…infinite series…’ and that is all we have. As we continue to date various realities we find that some items are older an some are younger - but, all had a point that, prior to which, they did not exist.

Arguments like this are more like watching someone try to walk on air - they fail because there is nothing to support either them or their arguments. Some people may believe anything they wish - as long as what they believe allows for an escape hatch … something where ultimately responsibility is omitted from the equation. We can omit this by saying we are the center of chaotic uiverse where there are no rules and when we die we just cease to exist. But, you know, there are still these patterns that we see both inside and outside of ourselves. Health works in a predictable way - and so does disease… things can be totally uniquie (e.g., iris patterns in the human eye differe from left eye to right eye, from the eyes of identical twins an of course from everyone else - yet we all have iris patterns that allow for recognition and identification). How did this happen? I know I did not make it, and I don’t think you did either… There really is room for God, if we let Him in.“Unfortunately this argument is unsound. Although in a finite ordered series of causes the intermediate (or the earliest intermediate) is caused by the first item, this would not be so if there were an infinite series.
This is a circular argument. The argument states that everthing can be dated - and if we can not date it, does not mean it is ‘dateless’ only that we do not have the ability to set a date on it. As we look around the universe, change abounds. Stars suddenly become supernovas, new galixies are discovered - and if we are lucky, the quater mile long asteroid that will come clsoe to Earth will truly miss us! We have no evidence on Earth of anything lasting forever - and tht is because nothing does last forever. So, we are back to the finate nature of all matter and energy.Sir Issac Newton was right - things are constantly either falling apart or have fallen apart.
The second way says:
“Now in efficient causes it is not possible to go on to infinity, because in all efficient causes following in order, the first is the cause of the intermediate cause, and the intermediate is the cause of the ultimate cause, whether the intermediate cause be several, or only one.”
This ‘second way’ is basically like the first. Only God is infinite - and we can only address the finite. Ultimately, it comes down to three basic elements, change (entropy) is a constant and that can only be applied to matter or energy and these items do not continue to create themselves. The only variable here is the amount of time it takes. God is timeless.
Again, here he lists aspects of a series of finite efficient causes and concludes that because an infinite series wouldn’t have these aspects, then it cannot be. …
Personally, I think it is Mackie who has begged the question. The issue is the reality of the finite - it has real limits, and one of those limits is that it began a certain time - whether it was the Big Bang or when th sperm united with the egg. It is at that point that we can go backwards to find the Prime Mover.
Finally, there is also the issue of his question begging and modality. There are different kinds of possibility.
Metaphysical possibility is concerned with whether something (an event, or state of affairs etc.) can become ‘real’ or ‘actual’. IOW, whether something is actualizable.
Let’s look at this ‘first’ Finally (most people limit themselves to just one…One must be careful about how one applies logic - lest total error develops. For example the Ptolemaic theory of the universe was certainly logical, It really does look like the sun ‘rises’ and the sun ‘sets’.and vey elaborate tables and models were constructed to prove their false theory… but, they were all logical!
Of this I am certain: I did not make any of the universe. And, no one human - or Committee(!) I know or have ever heard about has taken credit for doing this. And, before the Second Law of Thermodynamics came into being - man knew that things have a beginning and they eventually end. Patterns mean there is a Pattern Maker. You can call this Creative Engergy whatever pleases you - but, a lot of people call Him God.
Finally, there is epistemic possibility: metaphysical possibility conditioned by a person’s beliefs and knowledge. For example, for some people it’s epistemically possible for God to have created everyone in hell, yet for the one who believes God’s perfect goodness precludes such an action, it won’t be epistemically possible.
So, what does he mean by saying an infinite regression isn’t possible? Such a regression certainly wouldn’t contradict any logical laws. And what beliefs of ours would preclude such a thing from being real? I can’t even imagine. This only skims the surface.
