During my first few days playing Minecraft, I actually had no idea what crafting was. This was maybe early to mid-2012, I can't remember but I started Minecraft I think 1.2, but I had no idea how to play MC and I was determined to not use guides and walkthroughs(though they were scarce anyways so...) but I would punch wood, grass, leaves, whatever. I'd spend ages punching stone thinking I'd run into an abandoned temple or something, anything and I remember coming across Diamonds, plentiful of Iron and Coal(bear in mind, I was around 6-7 at the time) and I'd punch EVERY ore or something different from stone that I came across. I don't think I found many if any diamonds but I did pass so much Iron and Gold and just obliterated them out of existence lmao
