Imagine there were some people a long, long time ago who believed that a really long animal, like a snake, was super important and powerful. They even thought this animal could help them understand things about the world and maybe even connect them to the gods! So they started to do special things to show respect for the snake, like making art and sculptures of them, singing songs to them, and even sometimes sacrificing things to show their love.
They believed that the snake was a symbol of renewal and transformation, because it sheds its skin and becomes new again. They also thought that the snake could help them with healing, because some snakes have venom that can be used as medicine if it's used correctly.
Nowadays, some people still believe in the importance of snakes and worship them. But not everyone does, so it's important to remember that beliefs and traditions can vary a lot depending on where you are and what you grew up with.
