Revert and reset and very damaging Git commands

As a noob I have managed to completely delete all my local folder contents just by misusing reset and revert commands. Un-be-lievable! And no matter how many times I've tried I cannot return to where I was. The git reflog is not that helpful either... and only shows resets and not revert histories.

Gosh this is not good.

Why are these commands bypassing all the fundamentals of a computer OS. Surely if a file is deleted it should end up in the computer's rubbish bin. Not deleted permanently without a trace.

If that is the intent then there needs to be warnings etc. for deletes and overwrites.

I'm just amazed that all the basics of software design are ignored for the sake of convenience and speed.
