What are the 4 theories for the origin of the Earth?

This testament how God made the Earth

One of the 4 Origin theory that often involves creation myths

One of the 4 Origin Theory that are rooted in cultural beliefs

One of the 4 Origin Theory that explore the nature of reality, existence of the Earth

One of the 4 Origin Theory that are based on emperical evidence, observation, experimentation and logical reasoning

Believed in a primordial universe and explained that the original state of the cosmos was a primordial mixture of all its ingredients which existed in infinitesimally small fragments of themselves.

Greek philosophers believed in an atomic universe. They held that the universe was composed of very small, indivisible, and indestructible atoms. All of reality and all the objects in the universe are composed of different arrangements of these eternal atoms and an infinite void in which the atoms form different combinations and shapes.

The famous Greek philosophers proposed a geocentric universe where Earthstayed motionless in the heavens and everything is revolving around it.

An astronomer in 1543, with his theory of heliocentrism. He demonstrated that the motions of celestial objects can be explain withoutputting Earth in the center of the universe

In 1687, he described the universe as a static, steady-state, înfinite universe, In his description of the universe, matter on the large scale is uniformly distributed, and the universe in gravitationally balanced but essentially unstable

A model of the universe assumed by _____ was no different from Newton's in that it was a static, dynamically stable universe, which neither expanding nor contracting. He added a cosmological constant to his general theory of relativity equation to counteract the dynamic effect of gravity, which would have caused the universe to collapse.

It is the leading explanation about how the universe began . At its simplest , it says the universe as we know it started with a small singularity , inflated over the next 13.82 billion years to the cosmos that we know today

in Cosmology , a view that the universe is always expanding but maintaining a constant average density , with matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession

According to Paul Steinhardt and Alexander Vilenkin ( 1983 ) the inflationary phase of the universe's expansion lasts forever throughout most of the universe hence , continuously making other universes ( multiverses ) which could have different or similar governing physical laws .

Who proposed Eternal Inflation

this is an alternative solution to the question about the ending and beginning of our Universe . developed by Paul Steinhardt is a cosmological model that combines both the Big Bang and the Big Crunch as part of a cyclical event
