So what? Just because they are different, does not mean neither are true. If I have to guess someone’s name, for example, and am presented with two possible options, does not mean neither option is false, even if one is drastically different from the other. The reason for the drastic difference between Creation “theory” (I use quotation marks because Creation is not and has never been a theory, meaning it is not and has never been observed, tested, and supported by peer-reviewed evidence. As a result, considering Creation to be a valid explanation of how the Universe came to be is an odd choice.) and The Big Bang Theory is that Creation is based on a very old book, which has been time and time again observed to be largely false in terms of how it perceives reality, and science, and The Big Bang Theory is based on countless years of research, studies, experiments, observations, tests, and peer-reviewed evidence. Also, if we take into consideration the last three sentences of your conclusion, which are “If you only believe in facts, you'll take the current Big Bang evidence and make that what you believe in. Or, alternatively, you can have faith that a God exists and he created the Earth. That's all there is to it.”, then that means you pretty much admit that having faith in a God is distanced from facts, thus distanced from reality, thus having no value in the real world. So, if something is distanced from facts, why pass it off as real?
The fact that Crystal is using theology to try and prove a point is doing nothing but discrediting that point. Theology has never been observed to have any value in reality, besides people trying to bend their rules of theology whenever it is convenient for their argument.
