1 answer
The big bang theory says that the universe started from a tiny and super hot point called a singularity. This singularity exploded and expanded, creating everything we see in the universe today. It tells us that the universe is still expanding even now, and that galaxies, stars, and planets formed over billions of years. It's like a giant explosion that happened a really long time ago and keeps getting bigger every second.
