I agree with you and that is also my question. There is no answer though. So some will believe that it just randomly happened somehow and others see it as proof of a creator.
I see it as intelligent design but the fallacy of those who oppose that is they assume that admitting or believing in intelligent design means full acceptance of a religion or God belief. It could be that another advanced biological life form designed it and they are no longer around now, we are left trying to figure out our origins and what purpose of life. For now I believe we were designed, DNA as a coding language to design much life, and designed in a way to adapt and evolve. Beyond that, no idea atm. Who did it, why, if this is it, or an afterlife, etc.
