Cosmogony
Cosmogony is any scientific theory concerning the coming into existence, or origin, of the cosmos or universe, or about how what sentient beings perceive as "reality" came to be.

Usually, the philosophy of cause and effect needs a beginning, a first cause. Modal logic may only require a probability rather than a sequence of events. The concept of uncountable suggests an unknown somewhere between a finite number of likely rationales and an infinite number of possibilities.

From a sense of time as moving forward from yesterday to today and onward to tomorrow, there is again a suggestion of a prehistoric time before the first hominins.

The use of any system of thought or emotion to perceive reality suggests that some existences may precede others.

When more detail becomes available an existence may be transformed into something, an entity, a source, an object, a rocky object, or out of existence.

As a topic in astronomy, cosmogony deals with the origin of each astronomical entity.

Observation, for example, using radiation astronomy may provide some details.

Theoretical astronomy may provide some understanding, or at least some perspective.

In astronomy, cosmogony refers to the study of the origin of particular astrophysical objects or systems, and is most commonly used in reference to the origin of the solar system.
