You do understand the Information Paradox that Hawking proposed and other scientists were upset over? I understand that it is beyond basic Physics, and you might think that quantum mechanics is wrong?
I know about the Information paradox, though some of the math involved is beyond me. Current theory says there is no violation. But the fix is pure conjecture, of course, the problem is also pure conjecture. It is not like we have any black holes to try these things.
As for quantum mechanics being wrong? In general no, it is too well tested for those things that happen on the Earth. For corner cases that don't happen here, it is not only possible but very likely. Both QM and general relativity are incomplete and are sure to be so until they can be merged, and that merger will probably involve some alterations of the way things work.
This really has nothing to do with life on our scale though. In a quantum sense information can not be destroyed, but only because you might be able to reverse time and work backwards to recreate it. This is roughly like saying if I take a sledge hammer to a watermelon, the watermelon is still there because all the parts are there and I could put it back together.
