Evolution is believable because there is proof of it taking place. 80 years ago, rats could be successfully contained using the poison Warfarin, which stopped the rat’s blood from clotting. However, now the majority of the rats are unaffected by the poison. This is proof that the rats have evolved. It happened after a few rats become resistant, then the resistant rats breed to carry on the resistance to its offspring (through genes), so the rat population continues to survive. Something similar to this has been seen with what we call ‘Super Bugs’. These are diseases that keep on changing their DNA so they become immune to almost everything e.g. MRSA.
Evolution isn’t believable because, there are gaps in the fossil records. There are guesses at what this might be like neanderthals. There has been a skull discovered, but it could have been from one of the other periods. Also, there is a theory that aliens came down and planted all of the fossils and put things in volcanoes etc. People that believe this think they did this to trick everyone in the future. There are also gaps in the fossil records. This means that without fossils, there is no irrefutable evidence and without a complete proof, there is doubt.
Creationism is a religious belief that humanity, life, the Earth, and the universe were created in their original form by a deity (often the Abrahamic God of Judaism, Christianity and Islam) or deities, whose existence is presupposed. In relation to the creation-Evolution controversy the term creationism (or strict creationism) is commonly used to refer to religiously-motivated rejection of Evolution. They also believe that everything must have an inventor (like God creating the universe).
An argument for Creationism is, that some things are extremely comlicated, so therefore must have a craetor. They think, as the human body is too complicated to have been created by chance, it must have been made by God. This is explained in detail in the ‘watch maker analogy’. This says that a watch is extremely complicated so must have a designer. If that has an inventor, so must a human. Also, Christians might want to believe it, as it is part of their faith and believe that the Bible is right. If they didn’t believe it, they might think thy wouldn’t get in to heaven.
On the other hand, there is also arguments against Creationism. For example, anyone who is not a particularly religious person or an atheist, might think that since they don’t believe in the religion, they don’t believe in Creationism. This is because Also, there is no solid proof to say that Creationism is right, there are only theories to suggest this. If there was clear evidence that Creationism was correct, then there wouldn’t be so many other religions which are very popular.
To conclude, both evolution and creationism could work together as one theory. The design argument says that God created all things for a purpose, so in that case, perhaps evolution is just God working out the ‘bugs’ in the creatures; even divine beings aren’t infallible
