I don’t understand how do wells work. Like, I’ve seen a lot of wells made of stone, so, if you dig a huge hole in the ground, how does water come inside the well? Like, I’ve seen a lot of movies where someone gets stuck in a well or something, and there’s always a rock bottom. So, how does water get inside the well?

The rocks are just like sponge. Half of rocks volume or even higher is actually pores filled with water. These pores can be permeable so water easily flows through or can be impermeable so the rocks acts like a hydraulic barrier
