The Origins of Life on Earth

The video explores how we compute age, contrasting it with the complexity of determining Earth's age. Historically, Earth's age was believed to be only a few thousand years, but modern science estimates it to be around 4.6 billion years. The nebular theory, a widely accepted explanation, suggests that Earth and the solar system formed from a nebula, a cloud of gas and dust, following a supernova explosion. This process led to the formation of the Sun and planets, with Earth being the third planet from the Sun.

How did the explosion of a nearby star contribute to the formation of our solar system?

When do scientists believe Earth was formed?
