What is the origin of living things?

Answer 1

Creationism

God is the origin and the creator of all life. He created all that exists and all that exists.

Science

After the Earth had been formed over 4.6 billion years ago scientists believe that the energy from heat, lightning, or radioactive elements caused the formation of complex proteins and nucleic acids into strands of replicating genetic code. These molecules then organized and evolved to form the first simple forms of life. Those simplest forms evolved into all the life forms, all the animal and plant groups existent today. See link.

Answer 2

The biogenesis theory states that all living things can only be produced by living things and have no other way of coming into existence. This is the opposite from what is stated in the spontaneous theory.

Answer 3

It starts the male sex cell, or sperm fuses with the female sex cell, the egg. This then becomes the first cell, or in other words, the first form of life. This single cell then divides or multiplies into a bag of cells. After that, it continues the divide and multiply, making it grow in size and slowly looking like a human baby.

Answer 4

Biogenesis is the idea that life (on Earth, typically) came from some other life, like how humans give birth.

Usually people talk about Abiogenesis, which is currently the leading theory that attempts to explain how life began in the first place (life formed from some non-living matter).

Answer 5

Everything must have cells to live.
