The most profound question someone can ask is, “Who am I?” or “Where did I come from?” or “What am I doing here?” Why do human beings like believing that something exists, instead of nothing? Scholars argue that this is because something exists which provides the reason for its existence. Some of history’s best minds, scientists and philosophers, have tried to delve into the mysteries of the origin of the universe.

The universe constantly oscillates between expansion and collapse.
Aristotelian Universe: In the 4th century BCE, Aristotle propagated the theory of a geocentric universe with the spherical earth at the center.
It is surrounded by the concentric spheres of the stars and planets. Aristotle argues that that universe has a fixed size, but stressed the fact that it stays unchanged through posterity.
He suggested that the earth rotates annually around the sun in a circular orbit with a sphere of fixed stars. Aristarchus’s ideas were rejected in favor of Ptolemy and Aristotle, until it was revived by Copernicus 1800 years later.
Ptolemaic Universe: In the 2nd century AD, the Roman Egyptian astronomer and mathematician Ptolemy pioneered a geocentric model which was based largely on Aristotle’s ideas.
He suggested that the planets and the rest of the universe revolve around a stationary earth in circular motion. This was the most efficient astrophysical ideal of all time.

He demonstrated that the movements of celestial objects can be explained without putting the earth to rest in the center.
This was hailed as a landmark finding and is also known as the Copernican Revolution.
The Copernican Principle, which ejected the earth from enjoying the central position, helped establish cosmology as a science rather than as a wing of metaphysics.
However, the most popular theory about the origin of the universe is the Big Bang Theory which suggests that the universe originated out of a cosmic cataclysm unparalleled in the whole of history.
On the basis of scientific confirmation and philosophical argument, it can be concluded that the universe has a cause for its existence, though it is difficult to weigh one against the other.
So, how do you think the universe was created?
