I was seriously stoned many years ago when I had this epiphany

The lightning flashed, striking the field and setting it ablaze. As smoke filled the air, the apelike creatures were enveloped in the cloud and fled.

Having retreated back to the safety of their caves, they realized they were stoned as all get-out. The lightning had set a field of pot plants on fire and little monkey man was on the way to creating civilization as we know it today.

Putting 2 + 2 together they soon identified the plant that was responsible. The biggest problem was the odds of lightning striking a field of weed was minuscule and therefore someone needed to learn to control fire. And so it came to pass that in order to get high early man came to master fire.

Monkey man soon realized that tossing huge piles of the now sacred plant onto a bonfire was time consuming and wasteful. One clever stoner cleverly figured out that if you took an apple, scooped a small depression into it with a piece of flint and made a tubular hole with a stick connecting the depression to another part of the apple you could put light the weed and suck the smoke through the newly invented apple pipe. Early tool making.

Wandering the planet in search of the sticky icky was a full time job. Once a field was found the task of transporting it back to the cave was an arduous and time consuming task. That was until Oog figured out that a wheel would be the perfect solution. Make a wheel, stick it on a cart, bingo, moving the crop became child's play.

If only they didn't have to travel all the way from A to B just to score, life would be good. Also foraging for food when everyone has the munchies was just harshing everyone's mellow. The solution, plant the seeds and hang out at home instead of spending time out on the road. Small tribes that stayed in one place became the norm and as more caught on to the advantages, the birth of civilization, as it is acknowledged with the advent of agriculture, became a reality.
