I don't see how an infinite universe is logically absurd.
It has been explained to you.
Nothing has ever been observed to begin to exist from nothing, so it's a moot point.
Life hasn't been observed to come from nonlife, but that hasn't stopped you from believing that.
Second, if you believe that there was this infinite chain of past-eternal cause and effect relations...then you are right back at the wacky world of infinity.
Ehh... not sure what you're saying. I think you want the problem to be more complicated than it is.
Not at all...the problem is complicated enough...I will ask you the same thing I asked others on here (and they have also failed to give an adequate answer). So for example...
Just take the event of your birth. In order for you to be born, your parents had to come in to contact right? But in order for your parents to come in to contact, your grandparents had to come in to contact...and in order for your grandparents to come into contact, your great-grandparents had to come into contact, and so on, and so forth...
Now, if that chain can be extended into eternity past, then the chain itself is infinitely long, right? But it is obvious that if the chain itself is infinitely long, then the point of your birth could never come to past, because in order for any person in the chain to be born, an infinite amount of parents had to be born in order to "reach" any parent.
So if the past is eternal, to reach the moment of your birth, infinity would have to have been traversed..but infinity cannot be traversed in that manner, just like it can't be traversed if I asked you to count to infinity...you would never reach "infinity" as a final destination, any more than your birth could be "reached" as a destination if there were an infinite number of births which preceded yours.
See how that works?
Now consider the universe as a whole...it is in a constant state of change...if the past is eternal, then no change X could ever occur, because for every change X, an infinite amount of changes would have had to occur in order to reach the present change X...but that can't be possible any more than your birth would be possible should an infinite number of births preceded yours.
However, if there is a past-boundary to time...a beginning...a beginning of ALL beginnings, it would be easy for your birth to come to past, because there would be a finite number of events that preceded it.
So for example, hypothetically speaking, if Adam was the first human, as many humans that were born after Adam, the humans that were born between Adam and the very last baby born today is STILL a finite number...since there was a beginning...a start of the "chain".
This is a big philosophical problem for you and those that hold your view...and as I keep stressing, it doesn't matter what any mathematician, biologists, physicists, cosmologists say...there had to have been a beginning of all beginnings, and that is exactly why Genesis 1:1 states "IN THE BEGINNING".
You're making a bunch of empty claims that have never been demonstrated.
Looks like to me I just did, and if you think otherwise, I would expect you to have no problems demonstrating how the event of your birth can come to past if there was an infinite number of events that preceded it.
Like I said, no observation shows that the Universe came from nothing.
Um, no one is claiming that the universe came from nothing...the claim is that the universe came from God, and I think I've just demonstrated why a timeless cause was necessary...and again, if you think otherwise, I will anxiously await for your response to the above question.
You're the only one here who thinks it's all logically absurd due to a lack of understanding of the physical world
The good thing about the infinity argument is, one doesn't need to have an understanding of the physical world. That is irrelevant. In fact, Christian apologists were using this argument long before contemporary cosmology...an argument which is still valid and sound today, btw.
and a limited amount of knowledge.
You're like a flat-earth believer who can't comprehend how people can stick to a round sphere without falling off.
If you cannot provide an adequate answer to the question above, then it will be clear that I am not the one with the limited amount of knowledge.
And if there isn't an explanation then... hur dur, goddidit?
Well, if nature didn't do it, who is the next candidate? Anything but the G word, right?
Reading what someone says and saying it means more than what it says isn't analyzing. It's a lack of comprehension skills.
I simply described what state the Universe had 13.7 billion years ago, and you took that as me saying it was like that for eternity.
I lack comprehension skills? Dude, first of all, if you don't believe in God, then unless you believe that the universe popped in to being out of nothing, then you HAVE to believe that it is eternal. It isn't as if there are a million and 1 possibilities...either it popped out of nothing, God created it, or it is eternal. You don't believe in God, and I will assume that you don't believe that it popped out of nothing, so the only answer that remains is an ETERNAL universe that never began to exist, and by "universe" I mean all natural reality.
So in essence, I rightfully "took that as you saying it was like that from eternity". Or, some natural entity created it...whatever, either way, nature existed from eternity on your view, should you negate the God hypothesis.
