Classical Vs Operant Conditioning

There are many different theories about the creation of the world. The two that rival each other are the religious versions and the scientific version. The quote "They say that every atom in our bodies was once a part of a star", by Carl Sagan an astronomer, supports the scientific theory, which is being accepted as true more and more each day. What the quote tells us is that Carl Sagan believed in the Big Bang theory and the theory of evolution.

This quote supports the Big Bang theory in many ways. First, the big bang theory is the theory that the universe expanded and started to cool after a huge explosion that made planets and solar systems. When it's said that every atom in our body was once a part of a star it literally means that the first species here, bacteria, came from the earth which came from a star and we evolved from that. Which brings me to my next point.

Evolution is the main point if this quote. For us to have the atoms of stars in our body would have had to of evolved from the first things on this earth which were bacteria. As the bacteria and later animals continued evolving they kept passing on the atoms until they evolved in to humans. Many may not believe in the theory of evolution, but there are many findings that help prove it.

One of the findings that help support the theory of evolution is the Neanderthals. Neanderthals are people who started living around 190,000 years ago and died out only about 28,000 years ago. Neanderthals look very much like your modern man. They we a species made to endure hash weather and live off the land. Though they had a stronger build in body and a larger brain, when modern man showed up the Neanderthals died out. These people may well be our ancestors, but the point is that we are very much alike and the people before them alike the Neanderthals making it seem as we have evolved from them through a series of events.

Another finding that reinforces the theory of evolution is the recent finding of the little people in Flores, Indonesia. These people are not your average person, but are very much like us. These people that were found are a smaller species of human. They were about half our average weight and size but besides that we were very much alike. The species is hypothesized to have gone to the Island after some terrible event and the only people that could make it there were the small people. Then once they got on to the island the people mated and their offspring were the first in a new species. Without the theory of evolution how could you explain this phenomenon?

While the theory of evolutions is that everything evolved from single celled bacteria many need this proven to them to believe it,
