Your questions in your first statement are hard to come by...
BIG BANG:
QUOTE
how did it get there? why was it so small?why did it explode?how do they know this?
Ok, the big bang is simply a theory, let by the observations that we have seen. As you probably have heard of entropy, and how converting one form of energy into other forms, it does not lose energy, but it is converted into a less useable kind. This means that at one point in time, there must have been a date at which all or most energy was in the highest possible form. Otherwise any higher form of energy would not exsist, as it is simply a long road downhill from there.
The highest possible form of energy would be pure energy, as a famous theorist put it E = mc^2.
When you take particles into smaller and smaller bits, and you hit them at one another, it has been found that thy can be divided, and large amounts of energy are released. At one point all of these particles would have been simply that, one large amount of energy. It would not really have any defineable characterists. As it has been proven that many other forces, (gravity/electromagnetivity/strong force/weak force) Combing together when the energies of each are risen beyond certain points. It is thought of that eventually all things would convereg into one type of substance, it wouldn't really be energy or matter, but could make up either. That is the big bang. What was before that we cannot be certain of, because nothing really leads into that conclusion. (But my guess is that it has something to do with black holes, eventually eating our universe.)
It was small because that is the most likely reason behind our universe is expanding, although there are some theories floating around that it was a large thing/ there were several big bangs.
It exploded because it would have had so much potential energy, it was bound to happen. Read first paragraph.
How do thy know this, because thats what our studies and tests describe, you could be a world reknowned scientist if you can come up with a completely different explination for every test that points towards the big bang, that could be proven correct while the other theory is disproven. That is what makes anything science has to say makes sense, because that is what they think because of tests they have done. You can't test things for divine intervention, theres no way to prove or disprove anything.
BEGINING OF LIFE:
QUOTE
now how can rock and air create life?
Let me ask you, how can rock and air feed life?
It would make sence if we were made out of the same things to be replenished by them.
I'm sure you've heard of some experimnets that have been done in the feild of recreating life. How scientists have indeed made amino acids using the atmosphere of the primordial age and some electricity. But does that really constitute life? You would probably agree that it is simply some PART of life that alone cannot have any function... right?
But then, what if I said to you that there are several ideas that say that life developed from several parts, slowly. There is evidence behind this.
Mitochondria are known for being the machines in our cells that take glucose and trasform it into Adenosine Tri-phosphate, ATP for short, which is what is used as energy in our every part of our cells, and body. What you might not know is that it has been found that Mitochondria, this essential part of our cells, was probably not developed inside our cells to begin with. It is coverend with a lipid layer, which is the same stuff that acts as a cell wall. This means that the mitochondria itself was once a living organism, that had the job of simply converting one form of a substance into another. One other type of cell ate this small thing, and developed with it, making the host cell a more formidible life form because it could eat whatever it was eating before as well as the glucose that the mitochondria could produce. The same thing happens with other cell organelles, such as the Chloroplasts found in plant cells. I don't wish to delve further into this as I am getting tired of typing, but I hope you see what I'm trying to get at.
Early life was basically a bunch of reactions that could happen. They were not living or dead, but simply did a task of converting one substance into another. These in turn could be changed by some other enzymatic being into something further. You must keep in mind that many of the tasks involved in making the most complex protien chains known are simple tasks of taking out a water molecule, forming a bond instead. This is an extremely simple task as it takes a negatively charged end of a substance and connects it to a positively charged end of a substance, which link together and release the water into the area. As I said before, scientists have been known to have made amino acids, which if you simply take out a water from two, they start the formation of a protien, which is a much more powerfull peice of micro biology.
I shall continue this debate later, I'm going to bed.
