Even much, much earlier than the word “science” was coined, humans must have wondered about the world in which they lived, and have observed that certain things, certain events happened regularly and predictably.
Since dim antiquity, we humans have known that sunsets would be followed by nights, and then sunrise and daylight. We have known that (for those living in areas with four seasons) spring comes after winter, and summer before fall. We have known when to plant and when to harvest. We have known that when we sow corn seed, we will harvest corn and not rice or barley or wheat. We have known how long it takes for a woman to conceive and bear a child. We have known enough about how things work to be able to build houses, make clothes, make boats, carts, cars, trains, planes and other means to take us to places — and many, many other things to make our lives easier and more comfortable (or more complicated?!).
