The most important factor in determining the development of life on earth is:
temperature
water
distance from the sun
gravity

All of the choices are important to sustaining life on earth, but the most important factor is the earth's distance from the sun. This is because the earth's distance from the sun is just the right distance to create a surface temperature that is perfect for sustaining life. If the sun were to be just a little closer or farther from the earth, the planet's climate would drastically change; thus, affecting our waters, weather patterns, plant life, and animal life.
