However, there are many other factors at play that could influence the longevity of life on Earth. The planet's fate is not solely determined by its age, but also by a variety of external and internal factors.

One such factor is the evolution of the Sun. As the star ages, it will eventually enter the red giant phase, causing it to expand and grow hotter. This process will have a significant impact on the solar system, including Earth.

As the Sun expands, it will engulf the inner planets of the solar system, including Mercury and Venus. Earth's fate, however, is less certain. Depending on the timing and extent of the Sun's expansion, the planet could either be consumed by the star or pushed out of its current orbit.
