How did ancient humans see tall growing grass (wheat), think to harvest it, mill it, mix it with water then put the mixture into fire to make ‘bread’?

Question

I am trying to comprehend how something that required methodical steps and ‘good luck’ came to be a staple of civilisations for thousands of years. Thank you. (Sorry if this question isn’t correct for ELI5, I searched and couldn’t find it asked. Hope it’s in-bounds.)

A million monkeys at a million typewriters, but they’re all hungry.

Someone has literally eaten, dried, dismantled, ground, cooked, braised, battered, roasted, smoked, fried, everything, combined with everything else. Millions of years before entertainment, writing, we had the same overall brains, so learning, testing, experimenting was entertainment.
