The only real evidence that can be used at Loch Ness is the sonar findings... and they're inconclusive. The better, and later, sonar scans don't find the same shapes earlier did, and sonar can represent schools of fish as large objects.
It's worth noting to that the geology of Loch Ness doesn't support the idea of caves, and intense mappings of the Loch have not revealed any caves.
Many sightings seem to be of phantom waves, caused by the wedge shape of the lake reflecting boat wake back up to the surface.
(Similar to another famous glacier lake Lake Champlain, where similar sightings occur.)
Simply put sightings are not reliable.
It was so much easier to blame it on Them. It was bleakly depressing to think that They were Us. If it was Them, then nothing was anyone's fault. If it was us, what did that make Me? After all, I'm one of Us. I must be. I've certainly never thought of myself as one of Them. No one ever thinks of themselves as one of Them. We're always one of Us. It's Them that do the bad things.
