Both are faith based responses to questions we cannot answer any other way. Getting caught up in absolutes thinking your interpretation is the gold standard is a sign of an unrefined critical thinking process.
Both are theories about the world. 'Creationism' as a theory really only became pure faith very recently as most specific claims attributable to it have been disproven or better explanations have been found. For a long time it was a perfectly cogent theory.
You don't have to take evolution on faith. You can write a computer program that demonstrates that selection among almost-but-not-quite identical entities with heritable properties generates adaptive forms. Many people have.
DNA is real. Reproducing lifeforms are real. We know how they work in some detail. There's no faith required.
(Funnily, physics have come to acknowledge the same, but they call it dark matter and say it’s all very scientific, whatever it is. But this is unknown enough to be not worth much discussion.)
Regarding the evolution we see around us all the time, I and many creationists besides me have full confidence in the idea that micro-evolution does occur. That there is a stochastic gradient decent process that hones in on time-varying local maxima over generations cannot really be denied. But that provides absolutely no answer to the questions of abiogenesis and speciation en-masse.
I will say all of science is based on faith- the faith that the human mind can perceive the universe as it truly is, using rational thought and experimental data collection. For some reason this really bothers some scientists and they like to treat science as an unquestionable objective truth, but realistically, we can't exclude any number of hypotheses, but merely state them as improbable based on our understanding.
Really it boils down to whether you believe the laws of physics we observe now have been constant throughout time. If you do you’re called an evolutionist, if you don’t you’re called a creationist. Neither side has any proof, nor is any proof fundamentally possible.
The point being is, creationists have zero idea why they think 6,000 is some magic number in this case, other than bob said so in a book. But yea, books are written by men and men are liars. Even looking at things like RNA/DNA mutation rates in known species it's pretty damned easy to see that things have been around a whole lot longer than 6k years.
This is unknown and a quite anthropomorphic view on the universe. Just because we can create things doesn't mean we ourselves were created, even in the way you're talking about in the First Mover argument.
