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.)

Because anyone who’s hungry enough will try to eat anything at least once, even that weird grass outside.

Keep growing the weird grass untul it gets bigger.

Anyone with lots of food who’s bored enough will try random food preparation techniques until something they like gets made.

Multiply it by hundreds/thousands of years and you get a civilization with bread.
