Shovels
When people think of important inventions throughout history, they usually don't think about shovels. Imagine a world without shovels. Metal and other materials found underground would be scarce since mining without shovels would take so long. Houses would be much smaller because you couldn't create large foundations and farming would be almost impossible. Shovels influence our everday life and this website has all the reasons I think shovels are so important.
