You do realise that those are not contradictory. And that, in fact, science is supposed to be about verification, not assumption, and that whenever something has not been verified, it cannot be assumed.
If someone were to take either of those arguments and say they proved the negative, your complaint would have merit.
But any claim of scientific fact can be dismissed if it can be shown there is no verification of the assumptions.
The problem with applying scientific evolution to the mythology of origins is that we cannot observe initial conditions, and we cannot observe or repeat the past.
We can guess what happened in the past, and pretend that Occam’s razor is actually a scientific principle rather than a handy way of guessing at what happened, but we’ll never be able to say with certainty that a particular belief of the process of origins is the correct one.
After all, an all-powerful God could have created the universe 6000 years ago in precisely the state it would have to be in if it had evolved over billions of years. Sure, from a scientific perspective that would be “uninteresting”, but there’s no way to prove it didn’t happen.
See post 15. On what basis do we trust those lives to the proposition that those decay rates are constant?
There’s also an assumption here that TIME flows constantly and consistently... it might not, and the theory of relativity (and what we’ve been able to verify of it) suggests that is not the case.
