We would still be hunting and gathering with little time to invent anything, let alone the Internet. That's right, farming is the seed of civilization. Not quite literally, but without early man's discovery of using seeds to grow grain, we wouldn't have much of anything we have today. Growing your own food changed everything. Sure, hunting and gathering worked just fine for tens of thousands of years, but you couldn't do much else - no time. But when hunters and gatherers started planting seeds, they began to farm.
