We give to much credit to our ancestors

I was thinking about this yesterday, we give credit to our ancestors for many things, weathering the ice age, inventing religion, music, the creation of spices, creation of alcohol / wine, the wheel, the use of rice for food, salt as a condiment etc etc. The simplest reasoning is to think that everything came up randomly, by chance and through raw trial and error. Isnt it fishy that so many things came up through trial and error, agreed we are talking about thousands of years but look at the list of achievements wow thats a lot of success through mere trial and error.

Take rice for example, weve been eating rice since ages. I treat rice as a complex dish, in the sense you just cant eat rice raw like apples or mangoes or even vegetables, also by itself its just one grain and needs to be processed. It needs to be harvested, dehusked (maybe they didnt dehusk initially), cooked and then eaten. One cannot just eat one, you have a to gather a whole bunch of them, then boil them for an extended period of time (we assume fire already exists) and then eat them.
the simple explanation is, a whole bunch of rice grew together, and man used to look at the field and wonder as to what to do with those small seeds, they taste like stone especially with the husk and extremly time consuming to collect. He gets angry with his kids one day and tells them to gather a whole bunch, enough to fill a big pot (that will keep those brats busy for a day). The kids then labour on and leave this rice in a bowl (and probably with a whole bunch of pebbles to make up the volume, aha! the first adultrator hehe). It finally rains one day, pot gets filled with water, and then they eat it after many days, or their place catches fire due to a lighting or a wayward fire and this rice gets cooked (Let there be rice and then there was rice, enough to feed millions of people). Back to the story, this guy who was just trying to keep his kids busy, was rained upon, drenched, his place on fire, his stored stockpile of food destroyed, probably lost a few of his children, friends and wives (lucky him oops bad joke), notices that this thing rice tastes good now, he retraces the events that took place, and figures out aha I collect these thing called rice, put it in a pot, boil it and I will get food that tastes good and fills me up, hip hip hurrah chalk one point for humanity. Can you belive this.

This story looks straight out of a hollywood movie, similarly with making wine with grapes, making scotch and vodka and things more incredible like spices (that delicate blend), coffee, tea..... the list goes on, how lucky can man get, how smart or how many random strikes.
Another interesting thing is, lots of things evolved similarly in so many different palces, again going back to rice, Chinese have rice, Indians do, so do the Mexicans etc. Random acts in one place is say possible, but everywhere around the world hmmm.

I am not saying some alien race came and told us how to make rice, or something else happened, all I am trying to say is we might want to re-evaluate our history, our ancestors, and their accomplishments we take for granted. Leaving every explanation to evolution and chance chaos and randomness isnt going to cut the cheese (eeks make that mustard). we give them credit for figuring out way to many things.
