The Big Bang Theory

The Big Bang Theory is the most accepted theory of how the universe began. It states that prior to the Big Bang, everything that makes up the universe of today was found in a densely packed tiny point, called the point of singularity. It was all jumbled up and unorganized. Suddenly about 13.7 billion years ago it began to expand.

3 - Elements - Scientists have discovered the same elements found on Earth are also on other planets, asteroids, moons, and comets, all over our solar system. If the same elements are found all over, then everything must have come from the same source.
