I suspect that you are aware of the whole issue of how certain "parameters" of our universe seem, and I repeat seem, to have been selected to "just the right value" to allow for the evolution of life. One example is this famous thing about the rate of expansion of the universe - I am told that if it was just a teeny bit higher - no possibility of life, and a teeny bit lower - again, no possibility of life.
Well the rate of expansion isn't really relevant, because the rate of expansion is an end result of the very settings your are eluding. It has more to do with the settings of forces (for example if the weak nuclear force of hydrogen was increased by 4%, then there would be no hydrogen in the Universe, for it would have all been converted into helium shortly after the Big Bang, no hydrogen then no stars, no stars then no heavy elements and no life).
I hope you do not think that I am so naive as to claim that this clearly supports "intelligent design". However, I think it might, depending on other things. If ours is one of many universes whose "parameters" are set "by random", then sooner or later a universe will spring into being which has "just the right settings" - and it is only in that universe that life will evolve to ask the very question at issue. In such a case, the people in that universe cannot legitimately claim that their universe is designed any more than a lottery winner can claim that they have "divinely ordained" to win a lottery in which 30 million other people did not.
In such a case, its "simply a matter of probability" (this is a simplification, but I think you know what I mean) - sooner or later a universe with the "right" setting was bound to pop into existence.
Indeed, it seems special to us because we happen to be the ones alive in this universe standing in awe of the numbers involved.
But what if there is only one universe? How would we then account for it having "just the right settings"? We could propose at the least the following, I would suggest:
Well, you don't need many universes (although, I am a supporter of Lee Smolin's current theories, I will link something below) all you need is a simple natural mechanism for arranging the higher dimensional settings. For example if you had a huge amount of different sized balls in a box and you wanted just one size an easy way to sort them would be to have a hole in the bottom of the box that would either let only your ball through or stop your balls falling through, in the end you would have the desired balls but your system was nothing more then a hole. In the universe shortly after the big bang there would have been all sorts of forces at work but only the settings that can exist in our universe would win. Gravity isn't a wave or a particle but rather a dip in space time. All matter that has mass makes an impression in space time, it is the extent of the dip that equals the strength of the pull of gravity. It is this simple system that could in theory sort the universe into one in which hydrogen can form, and so on.
Lee Smolin wiki article said:
The theory surmises that a collapsing black hole causes the emergence of a new universe on the "other side", whose fundamental constant parameters (speed of light, Planck length and so forth) may differ slightly from those of the universe where the black hole collapsed. Each universe therefore gives rise to as many new universes as it has black holes. Thus the theory contains the evolutionary ideas of "reproduction" and "mutation" of universes, but has no direct analogue of natural selection. However, given any universe that can produce black holes that successfully spawn new universes, it is possible that some number of those universes will reach heat death of the universe with unsuccessful parameters. So, in a sense, fecundity cosmological natural selection is one where universes could die off before successfully reproducing, just as any Human can die without having children.

1. Incredible "good luck"
Luck would have had nothing to do with it. In fact, in a universe so vast it seems that we are not so lucky after all. Asteroids, viruses, black holes, gamma ray bursts, cold, heat...millions of things that would kill us, is it luck to be surrounded by so much danger? If it had been designed then it's not
much of a design. Sure, some parts of our little world are lovely
to our eyes but then that's more a case of the puddle sitting in the pothole looking around and thinking how perfectly designed the pothole is just for him, a humble puddle. Like the puddle we have adapted to parts of our world so it seems designed, and yes life may not have evolved at all in a different universe but then we can argue then maybe life would have evolved better in a different universe.
2. Logical necessity - the settings simply could not have been any different.
I think I covered this one already with my gravity/balls analogy.
The problem with an intelligent agent is that it must by necessity be more complicated than the universe you seek to explain by evoking it. The Intelligent agent also requires explanation, or else it becomes a none answer. Where did the creator come from? Where did all that complex data and knowledge come from? Where did it's inherent complexity come from? Where does it derive it's power? What created the Intelligent agent? Surely the parameters that have to be in effect to allow for the existence of such a powerful and some would argue perfect being have to be
even more precise than the ones we find in our own universe?
I am not sure that one can simply dismiss option number 3.
Because it's not an answer, it's a stop gap, a cop out. It's an even harder question to answer than the original because we can study and measure and observe the universe but we cannot study and measure and observe an Intelligent agent.
This is a complex issue, not least in terms of exactly what we mean by the term "randomness", but I will stop at this point.
It's an interesting issue indeed, complex issues are the best I think. I'm certain that very bright people will look long and hard for all the answers, I just hope they find some of the big ones in my life time. One of the biggest I think is "are we alone?", I think with 400 billion galaxies and each galaxy holding 200 billion stars then it has to be at the very least likely.
