We don't know anything about why quanta do what they do......we know WHAT they do, just like primitive hunters knew the way a wolf hunted, but he didn't understand WHY......just like we don't. And we don't figure to.....in fact, it's the majority scientific opinion (the Copenhagen interpretation) that we won't.
But people still somehow claim that science can explain everything. I believe in science and I believe in logic, but basing all your assumptions on the belief that human logic can explain everything is simply an example of anthropomorphic bias.
