Why do we not feel the heat and light of the stars eventhough they are so big and hot?

We don't feel the heat and light of stars like the Sun from vast distances because space is a vacuum, which means there's no medium to carry heat through conduction or convection. Additionally, the intensity of light and heat diminishes with distance due to the inverse square law, meaning that as the distance from a star increases, the energy received per unit area decreases significantly. While stars are indeed massive and hot, the immense distances between them and Earth reduce their effects on us to a manageable level.
