Yes, the gravitational attraction of the Earth is vital for life as we know it. Gravity is what keeps our planet in its stable orbit around the Sun, and it also provides the force that holds us to the Earth's surface.
Without gravity, everything on Earth would float off into space, including the atmosphere that we breathe. Additionally, gravity plays a crucial role in the formation of stars, galaxies, and other celestial bodies, which in turn can impact the formation and evolution of life.
While gravity can be dangerous in certain situations, such as falling from a great height, it is essential for the existence and sustenance of life on our planet.
