Get yourself a good lithics book or two. They may be expensive, but I'm sure you'll be able to find some on your particular area. Whatever you do, though, please don't collect, even if it's on your land. As soon as you start moving artifacts around, you are destroying a site and a piece of history. As much as you can, show respect both to the peoples of the past and those of the future by letting it be. If you really need stone tools of your own, get one of the books that teach you how to flintknap and make your own.

The recipe for life is not that complicated. There are a limited number of elements inside your body. Most of your mass is carbon, oxygen, hydrogen, sulfur, plus some nitrogen and phosphorous. There are a couple dozen other elements that are in there in trace amounts, but to a first approximation you're just a bag of carbon, oxygen, and hydrogen. Now, it turns out that the atmosphere is a bag of carbon, oxygen, and hydrogen as well, and it's not living. So the real issue here is, how do you take that carbon dioxide in the atmosphere (or methane in an early atmosphere) and water vapor and other sources of hydrogen—how do you take those simple, inorganic precursors and make them into the building blocks of life? There was a famous experiment done by Stanley Miller when he was a graduate student at the University of Chicago in the early 1950s. Miller essentially put methane, or natural gas, ammonia, hydrogen gas, and water vapor into a beaker. That wasn't a random mixture; at the time he did the experiment, that was at least one view of what the primordial atmosphere would have looked like. Then he did a brilliant thing. He simply put an electric charge through that mixture to simulate lightning going through an early atmosphere. After sitting around for a couple of days, all of a sudden there was this brown goo all over the reaction vessel. When he analyzed what was in the vessel, rather than only having methane and ammonia, he actually had amino acids, which are the building blocks of proteins. In fact, he had them in just about the same proportions you would find if you looked at organic matter in a meteorite. So the chemistry that Miller was discovering in this wonderful experiment was not some improbable chemistry, but a chemistry that is widely distributed throughout our solar system. The rest is evolution... survivl of the fittest advantageous features until... homosapien
