Accepting tradition in light of the contradictions towards reality

Hello Rabbi,
The Rabbi in the notebooks claims that tradition can be trusted if the content conveyed by it makes sense and the witnesses are trustworthy. That's a big deal.
The simple explanation.
But in the past, in moral Judaism, even if we start from a logical assumption, it will not match reality and therefore must be rejected.
For example, we know today that the world was created billions of years ago and that man was created through an evolutionary process, while the Torah says otherwise.
The Torah says, for example, about the flood, and in our time we know that this is not true. There is no geological evidence for the case.
Is tradition in these and similar cases really like a counterfeit bill? And are we supposed to reject it?
Isn't that right?
