As children, we tend to believe a variety of things, from nonsense ideas to respectable concepts. And more often than not, those beliefs are based on some form of teaching, like something our parents told us not to do lest something bad happen. As adults, we know certain things as a given; it came with the worldly experience over the years. But for children, anything that's not in their immediate sphere of expertise (assuming they have any) will likely be considered as the unknown, and kids then look up to others to fill in the blanks or come up with original ideas why things are the way they are. A Twitter user by the name of @Kristen_Arnett decided to delve a bit deeper into the topic, asking people on Twitter what are some of the beliefs they had as children.

"What’s something extremely bizarre you believed as a very young child?" was the question that kickstarted it all. Kristen Arnett wanted to know what, if any, believable theories users had as children—"believable" meaning not something about fairytales or zombies, but grounded in reality, with tangible reasoning behind it.
Of course, even when they are reality-based, those beliefs still don't quite make sense to an adult because they have fundamental knowledge of the world. We know that clouds are naturally occurring, not made of fabric. We also understand certain intricacies of biology that might seem alien as a child. Basically, while grounded, the beliefs are leaning towards naiveté and inexperience, rather than ingenuity or fantasy.
The thread wasn't meant to make fun of anyone, far from it. The answers people gave highlighted the difference in thinking, with children tending to take things quite literally, but still using their limited understanding and experiences to form a worldview that makes sense. It's the first steps towards greater understanding, and the more inquisitive a child is, the faster they understand the world they live in.
