How did life arise from nonliving compounds?
If the universe did begin with a rapid expansion, per the Big Bang theory, then life as we know it sprung from nonliving matter. Eventually, the reaction produced a number of amino acids – the building blocks of proteins and, by extension, life itself.
What is the major events of panspermia?
Panspermia (from Ancient Greek πᾶν (pan) ‘all’, and σπέρμα (sperma) ‘seed’) is the hypothesis that life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, planetoids, and also by spacecraft carrying unintended contamination by microorganisms.
How did God create the world?
In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. And God said, Let there be light: and there was light.
What are the theories in the formation of the universe?

What does the theory of panspermia propose?
The extraterrestrial or panspermia theories suggest that life existed in outer space and was transported by meteorites, asteroids, or comets to a receptive Earth. In this case the origin of life is not related to environments possible on the early Earth.
What are the different theories about origin of life?
Modern theory: The modern theory is also known as “chemical theory” or theory of primary abiogenesis. In the modern theory, the hypothesis of abiogenesis was proposed with a condition that the non-living materials can give rise to life in the condition of primitive earth.
What is abiogenesis theory?
Abiogenesis, the idea that life arose from nonlife more than 3.5 billion years ago on Earth. Abiogenesis proposes that the first life-forms generated were very simple and through a gradual process became increasingly complex.
