My premise is not only perfectly understandable but irrefutable. No matter how we look at it, in science and in our entire existence, we know of nothing that began to exist that was not caused to exist by something else already in existence. There is not a single example as far as we know, and so the logic is sound and not BS as you accused, nor irrational.
As to the Big Bang, it is the consensus of scientists that the universe began to exist at a particular moment in time, that before the Bang there was a non-dimensional singularity.
> Everything within the universe is made of the same material at the most basic level. So everything that is being "created" in the universe is not really being created- more like reassembled out of matter that already exists within the universe.
Just because it is of the same material doesn't speak at all to the causal mechanism that brought it about. Scientists agree that before the Big Bang matter did not exist.
> Because within the universe matter/energy cannot be created nor destroyed. So it is an incorrect comparison to compare the "creation" of anything within the universe to the creation of the universe.
The law of thermodynamics describes how the world works when, or provided that, the world is a closed (isolated) system, subject to no outside causal influence. Thus Sears and Zemanski’s standard text University Physics: "This is the principle of conservation of linear momentum: When no resultant external force acts on a system, the total momentum of the system remains constant in magnitude and direction" (italics theirs). They add that "the internal energy of an isolated system remains constant. This is the most general statement of the principle of conservation of energy." These principles, therefore, apply to isolated or closed systems. If so, however, there is nothing in them to prevent God from changing the velocity or direction of a particle. If he did so, obviously, energy would not be conserved in the system in question; but equally obviously, that system would not be closed, in which case the principle of conservation of energy would not apply to it.
> My point is that you cannot know that the matter itself follows this rule of needing a cause- because the only example of matter being created is the big bang, and as I said at the beginning, we cannot prove how the universe came into existence.
We can't prove how the universe came into existence, but it does follow that anything that had a beginning was cause to begin by something else. Current scientific understanding is that matter certainly did have a cause.
> natural disasters wreak havoc on innocent people and God does nothing
This is a completely different conversation, and I'm not sure we have room for it. Briefly I'll say that for God to continually mess with the cause-and-effect continuum that creates our weather and environmental systems is to wreak absolute havoc on life as we know it, and ultimately, (if I had time to walk you through the logic of it) negates science as we know it. It's an untenable solution to the dilemma. There is no clear contradiction here, as you assume. Actually, his constant interference to guarantee no natural disasters would be more disruptive and disastrous than letting the world function as he does. If you want to pursue this further, it's a different discussion.
> The reason that life on earth exists so impecibly well adapted is because of evolution
This is quite a faith statement. You attribute great qualities to random processes. From a naturalistic perspective, all change comes about by accident. "Purpose" has no place in a system that is purely chemical and governed by physics. Things just happen. Sometimes you get lucky, and sometimes you don't. The earth just has to by chance be in the right position, at the right angle, spinning at the right speed to create a certain wind, and lightning has to strike just at the right point and the right time when amino acids are near each other... All scientists will admit that it's not reasonable, but they'll say it happened to happen, and here we are!
The theistic perspective, however, makes more sense. As Plantinga says:
1. Science requires regularity, predictability, and constancy; it requires that our world conform to laws of nature. From the point of view of naturalists, the fact that our world displays the sort of regularity and lawlike behavior necessary for science is a bit of enormous cosmic luck, a not-to-be-expected bit of serendipity. But regularity and lawlikeness obviously fit well with the thought that God is a rational person who has created our world and instituted the laws of nature.
2. Not only must our world in fact manifest regularity and law-like behavior: for science to flourish, scientists and others must *believe* that it does. Whitehead: "There can be no living science unless there is a wide-spread instinctive conviction in the existence of an order of things." Such a conviction fits well with the theistic doctrine of the image of God.
3. Theism enables us to understand the necessity or inevitableness or inviolability of natural law: this necessity is to be explained and understood in terms of the difference between divine power and the power of finite creatures. Again, from the point of view of the naturalist, the character of these laws is something of an enigma. What is this alleged necessity they display, weaker than logical necessity, but necessity nonetheless? What, if anything, explains that fact that these laws govern what happens? What reason if any is there for expecting them to continue to govern these phenomena? Theism provides a natural answer to these questions; naturalism stands mute before them.
Naturalism claims that life itself developed from non-living matter without any special creative activity of God but just by virtue of processed described by the ordinary laws of physics, chemistry, and biology. But it's just as possible, and actually more rational, to believe that a designer caused the design, that the process was not all random but had input from an intelligent guide, and that intelligence, information, and personality came from an intelligent, informational, personal source. It makes more sense that the mind came from an intelligent source than that it arose accidentally from purely incogitative matter.
> but the science behind evolution is solid- and logical.
For science to be successful, the world must display a high degree of regularity and predictability (back to your natural disasters question). We couldn't drive our cars if roads could suddenly turn to oceans, or metal to goop. Intentional action requires a high degree of stability, predictability, and regularity. And of course the predictability in question has to be predictable by us. For intentional action to be possible, it must be the case that we, given our cognitive faculties, can often or usually predict what will happen next. Science also requires cognitive faculties to learn it and understand it. It’s an essential part of theistic religion—at any rate Christian theistic religion—to think of God as providentially governing the world in such a way as to provide that kind of stability and regularity. Without natural laws, science would be impossible. Science also requires that we can discover those laws. Again, theism makes it reasonable that we can understand what these laws are like.
You claim, as do others, that modern science has exposed theism as poppycock and superstition, but this is an error. First of all, there is nothing in naturalism that requires or proves that God doesn't exist. God could easily have orchestrated the evolutionary process, and a scientist wouldn't be able to tell. On the other hand, naturalists such as yourself claim that the course of evolution is not directed, guided, or orchestrate; it displays no purpose, it is blind and unforeseen, and it has no goals (it can't).
Let's examine this a little: we have memories, intuitions, and perceptions. It's how we learn about our physical environment and reason our way to deductive connections. But if these attributes are not reliable (significantly better than 50%), all knowledge comes under doubt. Suppose you are a naturalist: you think there is no such person as God, and that we and our cognitive faculties have been cobbled together by natural selection. Can you then sensibly think that our cognitive faculties are for the most part reliable?
I say you can't. The probability of our cognitive faculties being reliable, given naturalism and evolution, is low. If naturalism and evolution are both truth, our cognitive faculties don't have a high chance of being reliable. Nietzsche said, "Only if we assume a God who is morally our like can 'truth' and the search for truth be at all something meaningful and promising of success. This God left aside, the question is permitted whether being deceived is not one of the conditions of life." Thomas Nagel: "If we came to believe that our capacity for objective theory (e.g., true beliefs) were the product of natural selection, that would warrant serious skepticism about its results." Barry Stroud: "There is an embarrassing absurdity in [naturalism] that is revealed as soon as the naturalist reflects and acknowledges that he believes his naturalistic theory of the world. … I mean he cannot it and consistently regard it as true." Patricia Churchland: "Boiled down to essentials, a nervous system enables the organism to succeed in the four Fs: feeding, fleeing, fighting, and reproducing. The principle chore of nervous systems it to get the body parts where they should be in order that the organism may survive. … Improvements in sensorimotor control confer an evolutionary advantage: a fancier style of representing is advantageous so long as it is geared to the organism’s way of life and enhances the organism's chances of survival. Truth, whatever that is, definitely takes the hindmost."
In other words, the primary function of our cognitive faculties is not discovering truth, but contributing to survival. Evolution says that our behavior is reasonably adaptive to the circumstances, and doesn't guarantee true beliefs. Our beliefs *might* be true, but there is no particular reason to think they *would* be: natural selection isn't interested in truth, but in appropriate behavior.
Darwin himself expresses serious doubts along these lines: "With me the horrid doubt always arises whether the convictions of man's mind, which has been developed from the mind of the lower animals, are of any value or at all trustworthy. Would any one trust in the convictions of a monkey's mind, if there are any convictions in such a mind?" Materialists believe that rising in the evolutionary scale eventuates in content properties. The question is this: What is the likelihood, given evolution and naturalism, that the content thus arising is in fact true? What is the likelihood, given naturalism, that our cognitive faculties are reliable, thereby producing mostly true beliefs? Therefore, even the belief in naturalism and evolution is not only suspect, but defeated. And if naturalism and evolution and evolution are self-defeating, they can't be rationally accepted. Theism is the more rational conclusion.
