The Big Bang Theory is widely accepted, but can't be proved. The essential result of this explosion was our solar system, which includes the planets of Jupiter, Mars, Venus, Saturn, Neptune, Mercury, Earth, Pluto, and Uranus. The earth had its first life forms some 4.0 billion years ago. Humans evolved about 50,000-100,000 years ago. The exact date is still in dispute and can't be confirmed.
Many questions remain unanswered.
Compared to the age of the earth, human existence is but a fraction of a second on a 24-hour clock in geologic time. The earth has gone through many stages and mankind is only a small part of its history. The Plate tectonic theory is the idea that plates carry the continents across great distances. It has been determined that there are about 20 rigid plates that are in slow, continuous motion. This movement is caused by heat driven convection cells in the molten rock deep below the crust.
