Let’s mention some of these "antropic" points as quoted by their defenders; 1-Oxygin level. 2- Atmospheric transparency, 3-moon gravity-earth interaction, 4- carbon dioxide level, 5- Jupiter’s influence and so on and on. These facts are correct and are not in dispute. It is the conclusion that they draw. The old saw, used over the centuries, “God did it” was many times revised when new discoveries were made.
The universe is so big that we hardly can comprehend the size of it, and we probably have observed only a small part of it. The conditions that will have to come together (fine tuning) looks nearly improbable, that’s the truth. We also can see that 99.99999% of the universe is hostile to life. Since the vastness and variety of circumstances in the observable universe, is so great that somewhere these combination might support life in a few of the “gazillions” of galaxies and the “gazillion” solar systems in a Galaxy. This favorable combination did happen a few times, by shear chance, at least once for sure, since we are here! (Odds are too great? Winning a lottery with odds of 5 million to one does not need 5 million draws to be won. It could be won tomorrow.). The shear weight of pure Chance is therefor overwhelming if compared to an unwarranted conclusion which is just made up.
The other question is, why would a Creator design an enormous universe, 99.9999999% hostile to life, if he/she could have done it with a flat plate, with a dome with lights over it, just like our ancient forefathers envisioned it.
Conclusion: The size and complexity of the universe, even if we don’t understand yet, whether it had a beginning or is eternal, why the nature’s laws are what they are, whether the big bang is a beginning or a phase, or whether there is a multiverse, point to the development of life being created by chance as we observe it. To jump to the “God did it “conclusion . that has been many times disproven in the past, is a fallacy.
