Evolution more rationtal than creationism/god

In my multiple discussions with creationists both online and in real life the one thing I always get asked is to show the evidence for evolution. Then once I have shown the evidence for evolution the question goes a step further and I get asked to show the evidence for the transitional fossils. (1) Another term that is used for transitional fossil is the term favored by creationists and is called the "missing link". Regardless of the nomenclature a transitional fossil can be defined as "fossils or organisms that show the intermediate states between an ancestral form and that of its descendants". (2) In my opinion, I think transitional fossils are the second most convincing evidence for evolution. The first piece of evidence which can not be doubted is DNA evidence. (3) However, in this debate I wish to discuss fossil evidence as it is an easy visual observation of evolution that does not require a scientific understanding of DNA evolution or even what DNA is. An example of fossil transitional forms is given here to show the unmistakable transitional form of the gray whale. From 50 million years ago we can see how the nostrils of the gray whales ancestor have moved from the front of the skull to the top of the skull in the modern day gray whale. Additionally,there are other features in these fossils that have changed such as teeth becoming smaller between the fossil from 50 million years ago and the gray whale skull today. Picture source. (1)These fossils of the gray whale should be evidence enough of transitional fossils, and evolution. However I would like to show evidence of an even more important transitional fossils for us humans. These fossils are the transitional forms between Chimpanzees and Humans. One of the biggest errors perpetuated by creationists is that we are descended from monkeys. (4) However, this is a complete misrepresentation of the evolution of man, as we are not descended from monkeys but rather share a common ancestry. (5) Additionally, it should be noted that chimpanzees are not monkeys but are in fact apes. In the figure below it is obvious to see that chimpanzees and humans share a common ancestor which lived between 3 and 2 million years ago. The difference between these fossils and they way the split into the two different branches towards humans and apes is defined using brain size and other defining skeletal characteristics. Picture source. (5)Looking at this figure above, it is obvious that there are multiple transitional fossils which bridge the gap between chimpanzees and humans. Another very important point to realize with regards to transitional forms of species is that they are able to exist at the same time as other species. This can be seen even in the recent Australopithecus sediba fossils which has been dated to between 1.8 to 2 million years ago and which coexisted at the same time as other Homo species. (6,7) This fossils and the other Homo species all branch the divide between chimpanzees and humans. More proof that transitional forms can exist at the same time as other species is noted in humans which share DNA with Neanderthals. (8) As Neanderthals and Humans are two different species the only way they can share DNA is if they lived at the same time and interbred. . http://news.bbc.co.uk...; width="478" height="303" />Picture source (8)In this argument I have tried to show the following three important points regarding evolution. (a) Transitional fossils exist, (b) transitional fossils exist showing that Humans and Chimpanzees shared a common ancestor and (c) that transitional species co-exist at the same time as other species. I think this brief argument shows that transitional fossils or the so called "missing links" do exist. These transitional fossils even exist to show that humans share a common ancestry with Chimpanzees. For this reason I believe we can safely say that these fossils prove without any doubt that evolution is a fact. I hand the debate back to my opponent and cant wait to hear his evidence for a creator.
