The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...

Crucial to this doctrine are the ideas that life comes from non-life and that no causal agent, such as a parent, is needed. Supposed examples included the seasonal generation of mice and other animals from the mud of the Nile , the emergence of fleas from inanimate matter such as dust, or the appearance of maggots in dead flesh.
In Book I, he argues that everything that comes into existence does so from a substratum. Therefore, if the underlying matter of the universe came into existence, it would come into existence from a substratum. But the nature of matter is precisely to be the substratum from which other things arise.
Creatio ex nihilo is the doctrine that all matter was created out of nothing by God in an initial or a beginning moment where the cosmos came into existence. [13] [14] The third-century founder of Neoplatonism, Plotinus, argued that the cosmos was instead an emanation from God.
Existence: Concrete, individual being-for-itself here and now. Existence precedes essence. The subjective existence of reality precedes and defines its nature. Who you are (your essence) is defined by what you do (your existence). Facticity (facticité): Broadly, facts about the world. More precisely, the For-itself's necessary connection with ...
The question does not include the timing of when anything came to exist. Some have suggested the possibility of an infinite regress, where, if an entity cannot come from nothing and this concept is mutually exclusive from something, there must have always been something that caused the previous effect, with this causal chain (either deterministic or probabilistic) extending infinitely back in ...
The economist Tyler Cowen calls the book "truly excellent, readable and informative". Cowen insists it is "a science book, not a 'race book'", stating that although it has engendered "some public controversy", he is confident that no attentive reader could feel "affirmed in racist beliefs". [4]
