Why do some scientists think that Jupiter's existence may have been critical for life to evolve on Earth?
A)It kicked out many comets from the inner solar system through gravitational encounters, thus ending the heavy bombardment phase of the solar system.
B)It prevented the Earth from migrating outward and thus ensured a stable climate.
C)Meteorites from Jupiter may have contained the bacteria that started life on Earth.
D)It stabilized the Earth's axis tilt and thus ensured a stable climate.
E)It prevented the Earth from migrating inward and thus ensured a stable climate.

Jupiter's strong gravitational force is believed to have played a crucial role in the early solar system by deflecting and ejecting many comets and asteroids that could have otherwise collided with Earth. This process is thought to have ended the heavy bombardment phase of the solar system, which would have made it difficult for life to evolve on Earth.
