Theist: “Scientific evidence changes as we evolve, so your belief in your evidence is the same as a Christian belief in god. You believe it won’t change, but history proves you wrong.”
My Reply: Firstly, well done! You have managed to pack quite a few logical fallacies into a single sentence. Briefly, they include:
- Tu quoque (“you too”) Fallacy – attempting to equate god-belief (faith and tradition-based beliefs) with scientific facts (the theory of evolution, for example), which have been established by rigorous tests, observations, successful predictions and an immense explanatory scope, not to mention that your god hypothesis is completely unfalsifiable, and therefore utterly useless. You may as well attribute the sunrise to the magic of a pink unicorn.
- Argumentum ad Ignorantiam (appeal to ignorance) – Your implication was that we don’t know what we will know in the future, therefore god.
- False Dichotomy Fallacy – You implied that just because science can be wrong, god must exist (A or B), which also overlaps into the ignorance fallacy.
- Non-Sequitur – “Scientific evidence changes,” so it is equivalent to Christian god-belief. This particular statement also contains the ‘False Analogy Fallacy,’ for you are attempting to compare two things (god-belief and scientific facts) that are not analogous at all.
I could go on and explain why scientists, generally speaking, do not BELIEVE in evolution, or any scientific theory, but I think epistemology would only confuse you. I also suggest you investigate denialism, which describes the cognitive error of denying established facts for ideological reasons, so I have attached a link to a great lecture series on scientific skepticism.
