? look it up: Origin of butter
Butter’s origins go back about 10,000 years to the time when our ancestors first began domesticating animals. Today, butter in its many flavorful forms is the world’s most popular fat.
Maybe for a long time butter was the only form of dairy that adults could enjoy without lactose intolerance.
Humans have existed far longer than 10,000 years. And ancestors for millions of years before that.
Recorded history is a drop in the bucket of overall history.
