Everything design we understand have no designer. Also for Mountain and snowflake, i really don’t understand the need of a designer, you are adding the concept just because it caution your believe, there is no reason to believe that.
About the “sun is at the right place” argument, if it where not at the right place, we would’nt be there to question how it was at the right place, i mean if you roll 10 time a dice with 6 face and you chosse that you will have a baby only if you get 10 time 6, then you roll. There is only 1/(6^10) chance you wil have a baby, if you don,t get 10 time 6, you won’t have a baby so he won’t question anything.
Also if you take all suns and all planet, the probability there is planet at the right place is high, also maybe there is a physical explanation why there is a planet at this place, and if not; there is a probabilictic explanation, so i don,t see anything special in it.
