For some darn reason, I am Stanley Aaron Tarrant born on January 10, 1981 on an air force base in Turkey.
Are you, or do you just think you are? How do you know you're not Emily Brown, a 22 year old Scottish Housewife who is simply dreaming that she is in fact Stanley Tarrant?
Aeithesists answer this question: why exactly am I Stan Tarrant?
You've asked a multitude of questions there, I'm not entirely sure what you are referring to, but I'll give it a go.
Firstly, you aren't Stanley Tarrant, you simply think you are. You're conscience identifies itself as Stanley Tarrant. However, I or any other independent observer would not necessarily identify you as such. Even your parent's definition of the entity known as Stanley Tarrant will differ in key ways from your own.
Do some key molecules have a "Stanley Tarrant" radioactive tag on them and when these molecules form into a white male body born on Jan 10, 1981 that is what my consciousness became??
No. Your consciousness is a product of your brain. There's the whole field of sociology, psychology and similar devoted to what makes your personality. Suffice it to say that the reason you are uniqu (to yourself at least) is partly because you cannot experience anyone else's conscience (we could all be Stanley Tarrant, but you'll never be any of us to find out) and partly because your own experiences from birth are unique to you.
To give an example, assume you had an identical twin which was exact in every detail. If this twin had had the exact same experiences as you yourself from birth, then that twin too would be Stanley Tarrant. If we seperated you at birth and sent your twin to Poland, then it would be very different to the Stanley Tarrant you are currently.
You can see it yourself. Think back to when you were eight. Is the eight year old Stanley Tarrant the exact same Stanley Tarrant you are at twenty six, or are their differences between the you then and the you now?
Science in this universe can't possibly explain the undeniable FACT that for some bloddy reason, I am a 26 year old white male human, and not a bird, another human, or a maggot.
Unless you have incredibly strange parents, it's biologically impossible for their offspring to be a bird or a maggot. Hence you would be human. You don't know though that there isn't some maggot sitting somewhere asking why it's a two month old maggot and not some 26 year old human called Stanley Tarrant

So, where the hell did I come from??? Lets just assume that I was conceived during sex between my parents on April 10, 1980, precisely 9 months before I was born. Well where was "Stanley Tarrant" on April 4th, 1979???? January 24, 1234???? Did I not exist at all???
No, you didn't exist. Assuming you followed the average development for a human, Stanley Tarrant wouldn't begin to exist until three or four months after he was born, and even then he wouldn't be aware of himself. Two years after his birth Stanley would be beginning to realise that he existed as an individual, conscious being. The rest of his life would see a constant re-evaluation and evolution of Stanley Tarrant.
Look at it this way, unless you've been in a coma since typing your post, the Stanley Tarrant which wrote it no longer exists. The Stanley Tarrant reading this is very similar, but not the exact same Stanley Tarrant. When you're 46 years old, the Stanley Tarrant you are then will be greatly different from the one you are now (or you could even be the 46 year old white female Stacy Tarrant, you never know). At 86, the 26 year old Stanley Tarrant will likely be nothing but a memory of the Stanley Tarrant of that time, although certain key parts of 26 year old Stanley may still be there, the majority will be incredibly different.
Well the UNDENIABLE FACT THAT I AM ALIVE AND COMMUNICATING TO YOU NOW means that somehow I came into this world into this body for some reason.
No it doesn't. Stanley Tarrant is a creation of that body, you did not come into that body and inhabit it like some parasite or Invasion of the Bodysnatchers style alien. You came from part of that body, an incredibly complex information processing unit called the brain, and without it you wouldn't exist. Your parents will have observed you develop alongside the physical development of the brain in the first few years of your life, and your parents, friends and colleagues will observe further developments in Stanley Tarrant as his brain collates, collects and processes new information and experiences. When you reach old age, then those same friends and colleagues will witness further changes in Stanley Tarrant as parts of the brain become impaired or shut down with the advance of age. Eventually, they will see Stanley Tarrant cease to exist as the brain finally shuts down for the last time. One thing we can state for a fact - they will never see Stanley Tarrant without his brain, or his brain without Stanley Tarrant (even if he ends up misplacing a few limbs or other organs

)
If it is true that I in fact, came from absoulte nothingness and total oblivion, then why would I think death is the end????
How would you exist without such a body? Death as we know it is not caused because your personality ends (look at those in a vegetative state or coma) but because the body does. Your body didn't come from nowhere, it came through the combination of cells from your parents.
If death puts me into a state of "nothingness" where I don't exist, then why wouldn't it be possible to come from "nothingness" into a new life????
If you were to live a new life again though, you wouldn't be Stanley Tarrant.
Theoretically, if the universe is infinite and therefore allows for infinite probability, then there's every chance you might pop back into existence at some point. Wouldn't be the kind of afterlife I think you'd be after though.
I guess put simply, somehow I got into this now 26 year old white male body. Why wouldn't "I" somehow pop into another body??
Because another body wouldn't necessarily generate the exact same electrical activity in the brain which creates you, nor would it undergo the precise and required experiences which give you your sense of self and personality. Without either, you cannot exist as Stanley Tarrant. To put it another way, every human alive at this moment in time generates similar electrical activity in the brain, and many will undergo similar experiences. Only one of them is Stanley Tarrant though.
Are the natural laws of the universe indicative of a design and therefore a creator or is it just humanities tendency to see patterns where there are none that make us think there are laws at all?
The problem is no scientific law is inviolate or absolute, many can be and are broken by various phenomena (especially when we start getting to quantum level). It's more a case of us developing loose patterns which prove true regularly enough to be useful.
