To me both are some sort of belief systems. People simply choose to follow one or another not because they are scientists, theologians or have specific compelling evidence but merely because they are free to choose what they believe in and when they choose, most people mainly follow the thoughts or teachings of others that they think can be trusted (whether right or wrong). In that sense, both Evolution and Creationism are similar. What do you think?
Specifically referiing to the phrase "To me both are some sort of belief systems" my answer is "Yes, but they are not equal". What you are saying is largely a re-interation of an on-going dispute between the social sciences and the natural sciences known as the "Science Wars". The social sciences and "post-modernists" criticise natural science as a "social construct" that is an idea and a human creation which is no more true than any other belief system (e.g. religion and creationism). The natural sciences (represented by "scientific realists") however will assert that scientific ideas are "real" and true, and that scientific knowledge
is knowledge of the objective world. This can be demonstrated by the success of natural science to master various natural processes and so they can be utilised in various ways (mainly in technology and better means and processes of production).
Whilst Evolution and creationism are both products of the human mind, the scientific method is by far superior in ensuring that the theory of evolution corresponds to data and evidence that has been collected. It is not perfect but if we expect omniscience and absolute cliams to truth we are asking for answers from dieties rather than people. It is possible to get creationists who are intelligent, articulate and well aruged but it relies primarily on philosophical challanges to the scientific method as representing an ideology in its own right ("atheistic-materialism") rather than examining the evidence and the methods which are used to complete the picture.
At a minimum, evolution is a more useful theory which allows us to harness already existing natural processes in the way that farm animals such as cattle and poultry can be breed down the generations for specific purposes such as milk or egg yield, meat quantity, etc, or in how dog and bird breeders can do the same thing for asethetic characitstics such as plummage. This was a well known process in the 19th century and was used by Darwin as evidence for natural selection by demonstrating "domestic selection" by man. He took those observations and went one step further by suggesting that changes in animal populations based on competition for food supply and sexual partners worked as a mechanism for "natural selection".
Creationists cannot cliam such scientific applications, even if they insist there are "moral" reasons for supporting creationism. However, that morality is built on the authority of the bible which can be challanged from a number of angles, both as a flawed historical document which has undergone a process of "chinese whispers" through selection of material, intepretion, re-interptration and re-writing by translators, but also as lacking "evidence" to support the view that such morality is objectively valid and demonstratably benifitial to it's adherents. Appeals to authority and tradition, whilst admittedly something that favours our social instincts to "belong" and feel rooted in historical and cultural norms- is not the same as arguing that it is "true". If you are looking for a true depicition of the natural world, evolution is what to look for.
