Here's a simplified explanation:
1. Giant clouds of gas and dust (nebulae) exist in space.
2. Gravity pulls these particles together.
3. As the cloud collapses, it heats up.
4. Eventually, the core becomes hot and dense enough for nuclear fusion to start.
5. Nuclear fusion releases immense energy, creating light and heat, and a star is born.
So, stars are not created by anyone but rather by the laws of physics acting on the vastness of space.
