1. What from the beginning? that would take a long time, and quite simply i doubt anyone knows the entire evolutionary lineage of everything including every single mutation. Basically DNA replicates, as it replicates errors occur. These errors allow for new proteins to be produced, these proteins effect different things in different ways. You'd need to read a lot of literature to get the full whack of evolution and i dont think im obliged to supply you with the lot of it, talkorigins is always a good start though.
2. As i replied to Nosyned this was badly put. Very badly in fact. Sorry about that. Basically your dna is more closely related to your close relatives, then cousins etc, then broader family, then probably ethnic origin, then humanity, then primates etc etc. It all sorta works back from there until you get a few extremely well conserved stretches of DNA that are found in almost everyting, these are generally to do with DNA replication, if the replicator machinery doesnt work you dont grow, no matter what you are.
3. Basically your working back from what we have today, in which case it will work back to some sort of primordial prokaryotic (i would imagine) cell, and then to some sort of replicating molecules. Like you said, everything came from something (until you get to the first which is abiogensis, not relevant to topic, but that first doesnt have to be at all advanced)
4. An overall increase in entropy in a closed system, we can choose for that system to be the universe if you wish. However just because theres a little bit of supposed order here doesnt mean overall there's a decrease in entropy. Unfortunatly im not a physicist and cannot take you through the specifics. However
The Second Law of Thermodynamics, Evolution, and
Probability seems to cover it nicely. I know you can offer me a return website with aig or similar, but quite simply unless your upto doing the maths yourself i doubt this will satisfy you, but at least look over it.
5. We can measure radioactive decay (i believe most dating methods use this in some form) by getting a reading for how fast something decays and using knowledge of how much of such a substance would be present, we can then determine the age of an object. If a fossil was found that after repeated testing always dated to 6 billion, well then some thinking would have to be done i suspect.
6. Like i said, take it up with someone who believes, as far as i can tell its all based on whether you take Genesis to be literal or not.
7. You misunderstood, these insects did not come from Wolbachia, they have Wolbachia living inside their cells. It is a symbiosis, possibly mutualism, possibly parasitism its hard to tell. However deciding on how this could have evolved (the wolbachia would have entered a species of insect as some point after they were fully developed), as with many of the parasites etc is an interesting line of study, as it requires much more in depth thought than just hey the plants produce oxygen, and that just happens to be what we breath.
I have no desire to cancel you out, i hardly know you. My only real desire on any of these boards is to increase my own knowledge, be it through debate or just reading the posts.
Personally i have seen you made claims about the second law of dynamics and not back it up even with a reference to back up your position, there are several websites out there that agree with you, and put up the numbers to proove it, perhaps referencing one of these would be sufficient.
I'm actually an adult, so kid seems a little derogoratory, but thanks for the good wishes, you too.

. I can gain satisfaction out of many things, not all of them are true (i mean i gain satisfaction that i am extremely good looking and irresistible to women, theres a chance it could be false tho 
). Personally i do not believe there is any purpose, just chance.
