Let's not kid ourselves, you are, in fact, asserting that those who do not accept your premise are not as intelligent as those that do. Don't deny it, please, for if you do, I won't believe you.
Mark, with due respect, when you assert that intelligent people MUST accept your premise and if they don't agree with you you are implying they are not intelligent if they don't agree with you, and by doing that, what you are doing is waiving a flag that says 'Hello folks, I am ignorant". Is that the flag you want to wave? You realize that intelligence, like all forms of awareness, occur in nature in layered levels. You have, in the ocean, and see if you can follow this analogy: in the ocean we have, mud crawlers, and at the surface, we have mammals that breath air, and then we have everything in between the mud and the surface. A mud crawler cannot fathom what it is like to be an intelligent, air breathing mammal, nor can an air breathing ocean going mammal know what it is like to be land based human and in this line of reasoning, NOR CAN YOU fathom what intelligent people, PERHAPS more intelligent than you, what they can know, or not know, people who are above your intellectual paygrade. Everyone has someone more intelligent than they are, there are no exceptions. Capiche? To make such a statement is a pseudo debate trick called 'Posturing', which is an attempt to puff oneself up so as to achieve a higher posture in the hopes that no one can question you. But, that is a logical fallacy.
Your assumption is that life cannot exist without god. But, what you mean is life cannot exist without a supremely intelligent designer. What you are doing is assuming the nature of God, and that is where your logic breaks down. How can we, mortal human beings, possibly fathom the true nature of God? Well, I'll give my two cents: In my view, there just may be a spiritual basis to life, which is, in my view, what God is, but it's not what religionists think, it's not an entity above all things designing things. As a pantheist, myself, I accept that the spiritual basis to life is just a spiritual river, and essence, a force, from which all life springs, but thing is, it happens in randomity. The evidence of the randomity of existence is overwhelming, there is no denying it. That doesn't preclude the concept that life could (and probably does) have a spiritual basis. I.E. "Chance'. But, see, assuming infinity, all that is possible, is inevitable. so, in essence, 'God' is an abstract concept called infinity, because as long as there is such a thing as infinity, and I suggest there is, all that is required for life to occur is that it is possible, and if it is possible, (and it IS possible) therefore, it is inevitable. Oh, it might take 50 trillion throws of the universal dice to occur, but note that ALL numbers are infinitesimally small compared to infinity.
That is the fact is that the 'ID" people fail to grasp. Note that I am not an atheist, I am more in the 'pantheist' category.
