Oh no...here goes.....
Signs of an intelligence behind the laws humans have discovered that govern the behavior of matter.
It's interesting, because one often looks at the universe this way: that is, here we are a part of this thing and that everything is harmonious and makes sense and, therefore, there ought to be some kind of universal being that created it as it is so aesthetically appealing to us (the order, etc.). However, it's important to think that it's appealing to us because we are a construct of it - not the other way around, in other words, our minds are part and parcel with the constructs of the universe, and so things that make "sense" to us are those things which pan out in the world. Think about your definition of the word "intelligent" for a minute - and realize that intelligence, as often defined by us humans, is the ability to grasp the world about you in a effective and constructive way; not the other way around - in other words, intelligence is dealing with the universe and its laws WELL. It seems natural that we, then, would see intelligence in the universe as it constantly pushes forward with the laws we try to graple with in order to make ourselves intelligent. It doesn't make much sense for a being of a universe to find NOT dealing with that universe as intelligent. Our reasoning was built upon IT, not seperate, and so to say that the universe is intelligent is basically rather obvious as it defines what we mean as intelligent. If the universal laws were completely different, then a being would see THAT as intelligent, or a universe with no laws, potentially. I think we often see ourselves as something seperate and partial, and something capable of juding the "intellect" of nature - but we are nature, and so it makes sense it it seems beautiful to us.
The existence of a universal moral law that appears in all cultures and that is written on the human heart.
The basic principles are the same for the human species - we eat, we procreate, we sleep, we die; and it makes sense, then, that morals (or the rules that we see as socially and personally acceptable) would be very similar. We all have two eyes, right? We all have two arms, right? Why would it not make sense for the constructs of our brains (and the results of those constructs being apparent in thought) be also similar.
The existence of the human conscience.
This is a wonderful mystery, but a mystery is all - not evidence, at least in my mind, of a supernatural being or something existential. We find our own thinking miraculous because we can see ourselves and see ourselves thinking, and see ourselves seeing ourselves thinking. We are the only judges of our thinking - so why not make it wonderful, eh?
The conclusion of some people is that all human needs are, in fact, met, but that some humans reject the answer because they cannot conceive of anything greater than themselves.
I'm not sure as thought I really understand what you're saying by this, but I THINK I do...correct me if I'm wrong.....
I will argue that I have a deeper and more dramatic feeling of a greater reality than most people who have a religion because I see that realities that fail to make sense to us do so not because there is some kind of secret plan that persists in nature, but simply because it extends SO MUCH FURTHER than our own consciousness can fathom. I argue that the feelings of religiosity persist in me deeper than someone who follows a definite religion as too much time is spent in those religions projecting human desires onto the universe, when, in all actuality, that's quite the insult to whatever greater reality lays beneath.
