Physics does not give the _ultimate_ explanation of anything. Neither does
any other human enterprise. Even to say that "God" is the ultimate cause of all
things leaves questions, for our knowledge of who God is and why God does things is
limited. But it is quite false to say that "physics does not really explain
anything." It explains some natural phenomena in terms of natural processes. Even
though that does not answer the question of why anything exists at all, it is hardly
"nothing."
