Answer 1

Cosmic background radiation provides evidence that **it verifies that the early universe was once extremely hot**. This radiation, known as the Cosmic Microwave Background (CMB), is a remnant of the heat from the Big Bang and supports the theory that the universe began in a very hot and dense state, cooling over time as it expanded.
