Newb to the forum!
Hello everybody, I'm new to this forum hoping to learn a thing or two. I have a 1995 Mazda Miata 1.8L. Added some pictures
Currently the engine is not running, wouldn't start. Would just click and click and click. I could crank the engine over by hand. The engine is on a stand in my garage completely disassembled right now. A few of my crank bearings were torn to shreds I'll try to add a picture later.
Is there supposed to be a hole/vent looking thing in the block under the crank? I believe passenger side.

If you could turn the engine by hand but could not with the key, then either the starter isn't getting enough juice or the starter is bad. The click-click implies the solenoid is engaging, so the starter is getting the signal to start. It might not start or run, but it will turn over if the starter is working and nothing in the engine is preventing it from turning.

My main concern is how my crankshaft bearings came to be in that shredded destroyed state. The metal fragments from the bearings have spread all through the engine, in the head, oil pan crank case etc. Is this engine salvageable or is it best to start over with a fresh engine.

The head gasket was slightly split, could this account for oil loss and in return cause of the bearing shred-age? I had just done a fresh oil change on the car, I have no idea if the previous owner used synthetic oil or not and I put conventional in. Would that cause a problem?

Synthetic vs conventional is not the issue.
The drain back hole in the block is normal.
If your bearings are bad then there is a problem with the pressure or volume or a breakdown of the oil itself.
Replace the engine unless you have the luxury of waiting for it to be rebuilt.
What do the actual faces of the rod and main bearings look like where they contact the crankshaft? Please give us pictures of the working surfaces.
