How do you know humans are capable of 'understanding' things to the extent of the universe?
An ant will have some understanding within its own world and to its own limits. Just like a human has understanding of how things work in their own world and to a higher degree. But even humans have limits to their understanding.
It is still just a theory. There have been many theories made by science before that turned out to be false. Humans don't even fully understand how things within their own world work yet. It will be a major surprise if they managed to work out what happened apparently 13 billion years ago.
...or just paranoid?
