'Creationism' is one of the many reasons I could no longer be a Jehovah's Witness. The Watchtower - who I thought would not lie (...) - did in fact lie, or at least distort scientific data, mis-quoted scientists, omitted new data, quoted outdated sources... Anything to support creationism and ridicule evolution theory. As I have researched more, I've found that other religious people and organizations are no different. They lie, cheat and distort in some sort of 'holy war' against evolution theory. There is no 'peer reviewing' of material. If someone says they've found evidence against evolution, it's swallowed fur and all. Often quoted with no sources.
The truth is that the only reason evolution theory is attacked, is because it challenges a literal understanding of Genesis. Had it been about something different, or the Bible hadn't had a creation story at all, evolution theory would be as solid in everyone's mind as any other scientific theory.
It's important to understand that evolution theory, as it currently stands, does not address the origin of life. Darwin did touch on that subject, but it is not part of the theory. The origin of life is dealt with in abiogenesis hypotheses, which are still not theories.
There are many facts of nature. It is a fact that when you drop an object from a height, it will fall to the ground. Einstein's general theory of relativity is the theory that explains how and why it happens. It is a fact that fossils are found in different strata of rock, oldest and least developed furthest down, and gradually more complex further up through time, layer by layer. The rock layers can be dated using several independent radiometric dating methods. It turns out it is so universal that certain fossils are found in certain strata, that one can see which strata are the oldest compared to others by looking at the fossils they contain. But to find out the age, one of course date the strata using said dating methods.
You will hear that there are no transitional fossils. Of course, there are numerous, from all types of animal and plant life. In fact, even so, one doesn't even have to look at fossils, one can look at living animals, because they have vestigial organs. Like whales and dolphins, which have non-functioning rudiments of hip bones and femurs etc. But if one does look at the fossils, there are numerous transitional forms that have functional limbs where these rudiments are now found.
If one wants to form some sort of alternative creation theory, one would have to explain why a creator would create myriads of slightly different animals each in their own successive time period. One would also have to explain why certain animals which live in utter darkness have rudimentary eyes, sometimes beneath the skin. It would be kinda strange to specially create them that way to live in dark regions. Plus many other examples.
In addition, there is evidence in biology. Biology shows that we are closely related to several animal groups, some closer than others. There are signs that two ape chromosomes at one time fused into one which is now found in humans. At least, human chromosome #2 shows signs of being just such a fusion (humans have 23 chromosome pairs, great apes have 24 pairs).
I could write a book, but I'll just say that whatever you do, at least research the latest work by reputable scientists before you make up your mind. I've just finished reading a book by paleontologist Donald Prothero called "Evolution: What the fossils say and why it matters." which I'll recommend. It covers most areas in depth, also claims by creationists.
YouTube is not a 'scientific source', but it doesn't stop it from being a good resource if one know what to look for. Here's one in a good series of videos: http://www.youtube.com/watch?v=7w57_P9DZJ4 You should watch that entire series.
