Bullpucky. Your "failed mythological view," in which you seem to refer to belief in God or god(s) or a supreme being or whatever you want to call it (except god belief, as that is an ugly, abominable use of language) is merely you saying "I don't believe that so it can't be true or valid."
Our "improved and verified understanding of the world" tells us nothing about gods. It can't, as those kinds of things are not in the purview of science. And any new understanding from philosophy has only sparked argument, not replaced any specific "mythological" (i.e., religious or theistic) view.
You are confusing a natural fact, which can be scientifically investigated, with a belief (faith) in something that cannot be scientifically investigated. The former can change when new evidence appears; the latter can have no evidence, only belief.
Your "new paradigm" is just your belief (faith) in how things are. The "old one" is not one, but many; also just beliefs. I reject yours (as in I don't believe it; you certainly have the right to believe it but not to require that anyone else believe it), as you reject all those of others.
Sufficient looking implies an ability to look everywhere. That is not possible. There are areas outside the realm of science. Nor is it likely you will know all the qualities of what you seek. You may know some, but to know all is a different matter.
You assume pterodactyls are extinct. You don't know it. They could exist on another planet, having been taken to a zoo there by aliens (not that I believe in this scenario, but it exists as a possibility). Your belief that pterodactyls are extinct becomes more likely if you limit it to Earth. However, if there are still undiscovered parts of the world, and if you haven't investigated every part of the discovered world, then again extinction is just a belief, not a certainty. Remember the Coelacanths.
And yet, that is exactly what you do.
