Completing the Theory

I'm one that's just looking for answers. Below I have listed questions to which I haven't found satisfactory explanations. Could someone explain some of these, or better reference me to some explanatory material.-Concerning abiogenesis, how was DNA introduced into any type of life? The iron-sulfur world theory (metabolism first) didn't give me a satisfactory answer, and the RNA world hypothesis (genetics first) doesn't explain how RNA came about.
-How can evolutionists be so confident when there is no solid or supported theory of abiogenesis?
-Has anyone done any statistical calculations to figure out approximately how many generations would have been needed to happen for human evolution?
-Apart from the physical evolution, is there any explanation why there is such a large gap in intelligences? If we are all on the same evolutionary chain, physically we would have been adapting, but wouldn't that also imply something for the level of intelligent life on earth?I'm unbias one way or the other. I would just like to see a more concrete theory form so this debate can end. So far it's a war of faith against incomplete scientific data.

These are actually four different topics: abiogeneis; the nature of science; human evolution; intelligence. Please pick one, then rewrite Message 1 (click the edit button). Change the title appropriately, also.From the Forum Guidelines:

3. When introducing a new topic, please keep the message narrowly focused. Do not include more than a few points.

Post a note when you're done and I'll take another look.
