Anaximander (610 BC-546 BC) was first to develop a cosmology, or systematic philosophical view of the world because he wrote oldest prose document about the Universe and the origins of life.
He was also the first one to conceive a mechanical model of the world..
The first “cosmologies” were based on creation myths in which one or more deities made the universe out of sheer will, or out of their bodily fluids, or of the carcass of some god they defeated, etc..
Our universe began with an explosion of space itself - the Big Bang.
Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed.
Gravity gradually drew matter together to form the first stars and the first galaxies..

In order to understand how the universe has changed from its initial simple state following the Big Bang into the magnificent universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed over time.
The universe is comprised of mostly hydrogen and helium..
A huge explosion, known as the Big Bang, then sent matter and energy expanding in all directions.
This Big Bang hypothesis led to more testable deductions.
One such deduction was that the temperature in deep space today should be several degrees above absolute zero..

Anthropocentric Universe: Both Plato and Pythagoras influenced the first logically consistent cosmological worldview, developed by the Greeks in the 4th century B.C.
This early cosmology was an extrapolation of the Greek theory of matter proposed by Empedocles..
