The Ice Age ended so that big animals got extinct then it got hotter, making it easier to grow crops and and so that river vallys melted to unlock fertile land.
Extinction and Scarcity - Some megafauna like Woolly Mammoths became extinct, and game animals became scarce due to climate change and overhunting, forcing humans to seek new sources of food.
Climate Change - Rising temperatures worldwide after the last ice age provided longer growing seasons, more rainfall, and drier land for cultivating wild grasses. Rivers became more swollen, making more areas of the world fertile for farming.
Fertile Lands - As humans migrated across the world, they realised that some areas of land were more fertile, like river valleys, and could support a greater variety of plants and animals. This enabled the settlers of these areas to rely on farming more than hunting.
Taste! - As foragers experimented with eating new plant and grain species, they may have prefered some foods over others. This may have led foragers to try and grow their own, resulting in farming.
Overpopulation - As humans got better at hunting and gathering, a small population boom happened. As populations rose, hunter-gatherers felt under pressure to find new food sources.

Collective Learning - Generations of foraging had led to knowledge about the best plant species to collect, grow and eat, and the right times of year to grow things.

Nomadic Lifestyles - As hunter-gatherers learnt to hunt herds of wild animals, they soon organised their settlements according to where the animals lived and grazed. Humans soon setup semi-permanent settlements, which gave them time to experiment and discover new plants and grains.
