What theory do most atheists believe about the creation of the earth?
Cosmologists and astrophysicists (people who study such matters) explain the creation of the Earth (the ball of solids, liquids and gases we live on) as the result of the mutual attraction and accumulation of matter created (either after the “Big Bang” or in process of continual conversion of matter into energy) through gravitational attraction and the pressure of light. The view is not the view of atheism but of science. As atheists have no supernatural belief to explain the existence of the Universe, the opinions and findings of science must, by default, be theirs.
