There is NO knowledge from this field except for rubbing evolution on us...our ancestors did just fine without knowing these fake stuff and we will do too.
So, "knowledge" is only what has immediate practical purpose? Or is "knowledge" only that which is compatible with your religious presumptions?
Clearly, nuclear physics has practical value--it generates energy, can be used as a weapon, can be used to diagnose and treat illnesses--but the implications of nuclear physics includes many things "our ancestors did just fine without knowing," including those practical aspects just mentioned, but also such "fake stuff" as a cosmology of a 13.8 billion year-old universe, the radiometric dating of the formation of the Earth at about 4.55 billion years ago, and the radiometric dating of dinosaur and many other fossils to between millions to hundreds of millions of years ago.
On the other hand, there is no mention in the Bible of all the practical things that the pursuit of knowledge has brought us...such as nuclear power, nuclear weapons, medical diagnosis, treatments for cancer and other illnesses, an understanding of biochemistry, physiology, genetics...Our ancestors did just fine without that knowledge--should we just drop all that as well? Or do we abandon everything we can learn unless it has an immediate use? That certainly seems to be your implication.
